    I hear the siren call and might indeed succumb sooner than I thought.

    But, after the recent onslaught of exhaust and suspension mods, I will have to wait a few months for any further mod to prove to my family that I am not totally out-of-control when it comes to my baby, er, my car. I HAVE to set a good example for my children: self-control, discipline, delayed gratification blah... blah... blah...

    Coldstart of 997 TT with Fabspeed exhaust. No high revs, because of the coldstart, so quite boring , but shot with a HD Cam and good sound quality.

    Congrats and thanks for sharing. You don't want to rev the engine to 6000-7000 a couple times for recording purpose?

    Some issues I am dealing with, in case you don't already know:

    I believe there is a "dirty little secret" about Sony, and I would assume, most consumer camcorders that affects a large number exhaust recordings: Camcorders' audio recording is in AUTO mode by default. That means the camcorder automatically TURNS DOWN the gain when the sound gets louder, as in when you rev the engine. True dynamic range from soft to loud is lost as a result. The louder exhaust will be suppressed to sound the same as the softer one.
    Therefore, for true comparison, IMHO it's a good idea to change to manual mode for the audio recording gain. Mine is a Sony HDR-HC9 and this can easily be done by going into the menu.

    When doing comparisons, you might want to keep distance of mic to car, mic to ground, and where the recording is made (garage vs. outdoor), are kept the same between the 2 exhausts. These parameters affect how the exhaust sound.

    Lastly, this mic is very much superior to the built-in mic: http://www.amazon.com/Rode-VIDEOMIC-Dire...3105&sr=8-1 . The low frequency response is in another league altogether.

    Have fun. Some Fabspeed's seem to have CEL problem, I assume not the latest generation?

    Re: My Audition of Cargraphic Exhaust

    cannga, you are right, the auto mode of the camcorder "destroys" the dynamic of the clip, but it was the first shot with my new HD cam, and i had no idea how to change in manual mode, but now i know

    Higher revs can be seen here, but the dynamic is also totally destroyed, the cam shuts down the volume at the beginning but you can hear the stones on the asphalt under my tiers 300m away

    http://vimeo.com/1461200

    ATTENTION: i played around with my editing software and vimeo, so this clip is just a joke

    And yes, Fedex brought a new set of sportcats today from Fabspeed - for free the first set brought up the CEL in slow traffic after 20.000 km of spirited driving

    Re: My Audition of Cargraphic Exhaust

    Final review after 2 months with the Cargraphic Exhaust, Loud Version. As previously mentioned, please take my review with a grain of salt. Although I've listened to a lot of exhaust systems, this is still a matter of personal preference, and I am an all-out audiophile who uses a Conrad Johnson tube pre-amp.

    More than any other mods in my car, the Cargraphic exhaust has caused me to behave in ways entirely inappropriate for my age. I've found myself revving my car at stop lights, revving my car in parking garages, even driving around looking for empty streets with tunnels so I could hear the thing at WOT! I realize these behaviors are borderline rude but sometimes I can't help it.
    Kidding aside, while it may not offer meaningful performance gain (one gets used to the seemingly quicker rpm climb) like the Bilstein PSS10, the Cargraphic mod accomplishes the same goal. It does things that wake up the Turbo and turns the car from a somewhat boring luxurious grand touring type to one with a vastly more aggressive and sporty character.

    1. Upon start up, the exhaust gives a delicious and "crunchy" (no other way to describe it) roar, then settles down to a lower frequency rumbling. While lasting only for a couple minutes, the initial roar is important because that's what you hear of your car first, and often.

    2. Once the car starts rolling, at low rpm, a low frequency rumbling that's not too loud and not too intrusive, yet definitely there. The low frequency component was an important criteria for me when I was shopping around: I don't like exhaust systems lacking in low frequency sound because they then lack a sense of heft/power. Yet, get this rumbling too loud and the neighbors will want to disown you, as low frequency noise is extremely bothersome to bystanders. The Cargraphic Loud strikes a perfect balance for a neighborhood-friendly car. In short, despite of the name, this system is not that loud at low rpm. If you want a really lound system at idle, you need to look elsewhere.

    3. Where does the excitement come from? A mid-range, not high-pitch roar that starts around 3000 rpm, becomes urgent and loud at 5000 rpm, and absolutely, positively screams at 7000 rpm. The roar changes in pitch and loudness as you go up the tachometer so that by red line, it is a gorgeous howl with a mechanical character not unlike those race cars I heard at the Long Beach GP (but, amazingly enough, still not nearly as loud).

    4. The downsides to all of this? One, cost (a lot more $$$ than American systems, but about same as other European systems). Two, Porsche does such a good job of insulating and sound proofing in the Turbo, that you do not hear nearly as much unless the window is down, or you are up there in rev band, or when you are in a tunnel. I still believe that the most spectacular sound from this system is reserved for spectators, those standing on the sidewalk when you do a fly-by at speed. The machine-gun like staccato burst is guaranteed to be jaw dropping!

    5. While the Cargraphic Loud wouldn't take you to the gold standard, in my mind that belongs to the howl of a Lamborghini -- orgasmic is the word that comes to mind, it is now way up there, an extremely exciting sound that I could recommend without reservation. Shoppers might want to pay attention to the post above by "sharkster." His shop is one of California's most reputable Porsche specialists; listen to what he has to say about the Cargraphic Loud. http://www.sharkwerks.com/products.php?model_id=1&type=Exhaust
    That said, bottom line is you still have to listen with your own ears and probably a good idea to NEVER rely solely on internet video and sound clips (see explanation in the 2 posts above this).

    Oh, almost forgot to mention I got a US $375 traffic ticket the second or third week of ownership, while test-listening to the sound. First ticket in a number of years and first time in a Porsche. As you already know, to hear the exhaust you need to go a touch faster than normal; I was so happy listening to the exhaust's scream that I didn't pay attention to the radar. Cop was NOT pleased (didn't you *HEAR* my siren? )

    Re: My Audition of Cargraphic Exhaust

    On another note if anyone following this tread is interested I am selling my cargraphic stage 1 (due to the purchase of the titanium gt2 exhaust). It has 10k kms and also I have another set of almost new silencers that cargraphic made for me to reduce sound a bit. I don't know why they call it cargraphic stage one but compared to a stage 2 I tried it sounded the same (especially under full throttle).. As far as noise is concerned it recorded 102db at 4500 standstill and over 110-115db flyby full throttle (bedford measured that). Any interest pls PM me.

    Re: My Audition of Cargraphic Exhaust

    GT, gl with the sale, try selling on 6 speed as well, very active fs section with a ton of traffic.

    Re: My Audition of Cargraphic Exhaust

    Yeah this Cargraphic seems to switch me into the "juvenile delinquent" mode all the times . Oh well, anything to feel young again.

    My work place has a 5 level parking structure that has enclosed walls so the sound does reverberate more than normal. Even though I (obviously) only drive at slow speed in the structure and the exhaust is not that loud at idle, it makes such a disctinctive sound that a co-worker told me the other day she could tell when my car comes through the gate. She didn't look mad so I assume she has great taste also.

    Unfortunately, because the opening and therefore direction of sound of the exhaust is backwards away from your ears, I believe the only ways to hear the full siren song at speed are a. standing outside, b. buzzing another car at close range (this frightens people so I only do it for a selected few), or c. going through a tunnel. Going through tunnels with windows down remains my favorite and is another source of happiness in life. It sounds like a race car screaming for others to clear the "approach" -- so mean, so "mechanical," so beautiful! I did not expect this exhaust to affect me so much, but it does. I must share the excitement here since my wife most definitely does not understand this one.

    Re: My Audition of Cargraphic Exhaust

    I don't know how you guys with the loud version can show yourselves in public!

    Seriously, I have the 'medium' loud CG version and after 5500rpm it sounds so angry that I have been told by following motorists with their windows down that it physically hurts their ears under full acceleration!


    Re: My Audition of Cargraphic Exhaust

    Same here with the "quiet" version..!

    Re: My Audition of Cargraphic Exhaust

    hahahah

    so now we come to the conclusion that loud,medium and quite CG exhaust are the instead the SAME exhaust


    Re: My Audition of Cargraphic Exhaust

    Same or indeed almost the same!
    Actually I asked them if possible to send a more quiet version that does not have that resonance problem (between 2.2-2.8k rpm) and they said it was possible and make a set of silencers. The outcome was that the overall sound is indeed a bit less, resonance though was the same as level 1, level 2 systems..

    Re: My Audition of Cargraphic Exhaust

    I rode in a cg loud yesterday, thanks Roy. But, the thing droned like a muther, my ears are still ringing. The best exhaust out there for a turbo that doesn't drone is the........tubi.

    agreed on the drone.. Actually I have not heard the tubi but the GT2 titanium one does not drone and wiht a set of 200 or 300 cats is good for 650-700hp apparently. I took a drive in a Oakley car that had this exhaust and wsas impressed with how docile it was..

    >>>>>>>>>>>
    I have droning on the Tubi between 2500 and 3000 rpm in fifth and sixth. It is becoming less as I put more miles on it. Currently at 800. (Owner still had resonance when I checked with him later.)
    >>>>>>>>>>>>>
    I have some droning with my Tubi at 2800RPM
    >>>>>>>>>>>>>>>>>>

    The issue of droning has always puzzled me. I think that if you search enough, the chance is high that you will see droning reported with any after-market exhaust system. When my Turbo was stock, I remember a slight resonance in the exhaust below 3000 rpm, not as much in 1st and 2nd gear, more in 3rd-6th gears. It was a very slight hum noise, most around 2400-2700 rpm in my car IIRC.
    I believe that any after-market exhaust system that amplifies sound -- a must to make it sound good , will make this hum more noticeable; it has to. What is unclear to me is, among all knowledgeable 997 owners with (assuming!) good installers, why some report none & other insist there is a resonance. My *guess* is the problem is there, just that some ears are more sensitive to others, and one could never discount variations in the cars and the installation methods.

    As another example of if you look enough, you will find reports of droning, again with the Tubi: When I test drove the Turbo that belongs to a forum member here (Dick/dkreidel), I thought the resonance is NO WORSE than stock, which would make it the least of any I've heard, but Dick, whose perception and engineering skill I wouldn't question , told me that there is a resonance around 2600 with the Tubi, I just haven't heard it! How do I reconcile Dick's observation with yours? I can't!

    Without a doubt, I think the Tubi has the least resonance problem. So why didn't I pick it?
    1. I couldn't confirm whether I was wrong in sensing a loss of low end punch with the Tubi installed (a possibility since there were so many variables during the test drive, but I can't deny what I sensed). Dick mentioned a loss of 20 lbs-ft torque in his dyno below 2000 rpm before subsequent gain at higher rpm; how important this is, or whether this could be sensed, I don't know. Just didn't want to take a chance, especially because:
    2. The Tubi has great reputation, one of the most well known companies in exhaust systems, the least resonance, great construction, popular among many, but in the end, the sound is just not what I was looking for (it's all about me ). This is strictly a matter of personal preference, although I do think that it should be high on the list for people with convertibles.

    In other words, I picked Cargraphic knowing that it has more resonance. In fact, all 3 systems that I like, Cargraphic/AWE/GMG, have 2 things in common to my ears (YMMV): more low frequency heft/rumbling (which is critical to me) and more resonance below 3000 rpm than the Tubi! The resonance is a necessary tradeoff -- like suspension nothing comes free, and just doesn't bother me, perhaps because I often cruise at 3000 rpm or above, where there is less Turbo lag. In other words both my highest recommendation for Cargraphic and, more importantly, live auditions, stay!

    Re: My Audition of Cargraphic Exhaust

    Alex,

    Yes I know. I'm no longer the responsible and law-abiding citizen I used to be.

    Amazingly enough I rev this car so much that my mileage has taken a nose dive lately. Depending on the situations of course, I've seen 12 mpg reported sometimes. My carbon footprint has gone to ***t. All because of this silly exhaust system.

    I do have a regret. Why I didn't get it sooner! With Bilstein and Cargraphic, I am H-A-P-P-Y.

    Re: My Audition of Cargraphic Exhaust

    Can is right about a number of things, the most important being a requirement to do a live audition of any exhaust you are considering. I took a chance on my Tubi, as i couldn't find anyone in SoCal with a 997TT Tubi. I was lucky, because it was exactly what I was looking for. I like the higher pitch of the Tubi; Can digs the low frequency rumble. Blondes and brunettes I guess. Now that I have about 5,000 miles on my Tubi the resonance that I heard/felt and Can didn't perceive is definitely decreasing, and the exhaust is getting louder and "angrier" - what a glorious noise when it's wrapped tight!

    Yes I saw this at the US Cargraphic office when my exhaust was being installed. The only thing I don't like about it is that it's chrome; I prefer something less shiny, like the brushed silver finish in OEM 911, or stainless steel like my Fabspeed tip. And it's still slightly oval, where I want perfect round.

    But yes, if the finish and shape is what you like, the thing looks to be very well made, and IIRC, would be lighter than my Fabspeed tip.

    Re: My Audition of Cargraphic Exhaust

    Alex, you must have overlooked that or never looked before. Cargraphic has had those oval tips offered for a while. I had these originally on mine.


    The problem is that these tips are sensitive to extreme heat emitted by the turbos. They started turning brown on me and so I had them powdercoated black which didn't last very long. I then had them ceramic coated black which lasted a while. That is until some dirt got baked on them ruining the finish. I ended up taking them off altogether and going back to the stock tips. I've since then installed the TechArt tips which has held up against turning brown so far.

    Re: My Audition of Cargraphic Exhaust

    I recently post the following on 6speedonline -- sort of a summary of my experience, of what to listen for, etc.

    Just some thoughts from my own experience. Although I picked the Cargraphic, IMHO there is no such thing as the "best" system since we all differ in what we’re looking for. Also, do not trust video/audio clips on the internet; there are many reasons but bottom line is they tend to be grossly inaccurate. A live audition is almost a must.

    Three things I would listen for (YMMV): loudness, frequency (in particular the low frequency rumbling, important to me because it gives a sense of power), and character (some system has a continuous roar as RPM climbs, other has more of a staccato sound).
    Keep in mind, at low rpm, the low frequency sound dominates. You will hear more of the mechanical scream only as RPM climbs. It’s almost as if there are 2 phases you are listening for.

    Inside versus Outside: Exhaust systems sound totally different whether you are inside driving or outside as a spectator. Inside: sound is quieter and you hear a lot less of the rumbling and high frequency scream (The only way to overcome this problem, short of getting someone else to drive your car at WOT, is to take your car through tunnels with windows down. ). Keep this in mind during your auditions.

    My opinions of the 4 systems that I've listened to:

    Tubi: Great reputation, great construction, but not that loud. In fact a little too quiet for my taste. The low frequency component is not strong in comparison to others, and this is the main reason I didn’t pick this system (others have remarked on this character of the Tubi sound). If long comfortable trips are important to you or if you are stuck in traffic often, this is the one.

    AWE: At idle and low rpm, lovely low frequency rumbling that reminds me most of the non-Turbo 997 sound. On throttle: starts to scream with a sound more continuous in nature. If it weren’t for the Cargraphic, I would own this one. Additionally, AWE undercuts all other systems significantly in price, especially when AWE is having a sale. Both the AWE and the Cargraphic Loud are docile at low RPM; no need to worry about the neighbors here.

    Cargraphic: At idle: Nice low frequency rumbling that seems to become deeper after a few months of ownership. A little throttle at stop sign: delicious mid-bass/mid-range crunchy and throaty roar that feels oh-so-good Smiley. Hearing this car in the tunnel at WOT, or have someone does a fly-by while you are on the sidewalk, is guaranteed to be an experience you will not forget. It’s an absolute mechanical race-car like scream inside the car, and a spectacular staccato mcahine-gun like burst if you are outside. Around the neighborhood at low rpm, it is docile.

    GMG: Love this one too. Very aggressive and loud. Very strong low frequency rumbling. My audition of this system is shorter than the other one so I can’t comment as much. It might be a little too loud but I would have to listen again to make sure. I believe the GMG has a real quad outlet (not fake like the others), and I like that.

    Re: My Audition of Cargraphic Exhaust

    On issues of the "perfect exhaust," resonance, and power gain:

    My experience so far indicates that unfortunately, like suspension mod, I could have an exhaust that's comfortable for relaxed cruising, or one that is loud and aggressive enough for me, but not both.
    With my Cargraphic Loud, about 80% of the time I think it's perfect, 10% of the time I think it's not loud enough, 10% of the time I think it's too loud. 80 is hardly a perfect mark, yet I am perfectly happy because I know this is about as good as it gets (and anyone claiming otherwise might be blowing smoke).

    Resonance: I do not believe there is a popular after-market system that someone somewhere has NOT complained of some resonance issue. It doesn’t exist. My theory: Even the stock exhaust has a hum at 2500-2700, particularly in the higher gears, beginning with 3rd and worse in 4th and 5th (my car does not see 6th LOL). Any system that increases loudness (i.e. all after-market exhausts) will increase this hum level. It occurs only at cruising (never when you are going through the gears quickly) does not bother me at all because I cruise at 3000 or so, when the Turbo lag is minimal. The bottom line: Check if any Tubi or Cargraphic or AWE owners return their exhausts because of resonance? The answer is hardly ever.

    Performance Gain: Although there are dyno's from AWE & Cargraphic of power gain, I've heard of a couple of anecdotal cases of subjective or objective low end torque loss with after market exhausts. (I've not seen exhaust-only dyno's from GMG or Tubi. GMG has one with GIAC. Tubi, curiously enough and quite puzzling really, doesn't seem to publish a dyno.) So to tell you the truth I actually felt happy that my car felt the same after the Cargraphic installation. It does rev up a little faster from 2k to 3k, but no apparent power gain that I could feel.
    Incidentally the Cargraphic Exhaust is made and developed by the same manufacturer who does the Cup exhaust systems of the 996/997 in Europe, RS Tuning, based in England. To me this is a very nice assurance.

    997 Turbo + Bilstein PSS10 (Review) + Cargraphic Exhaust (Heavenly Race Car Noise Smiley Review)

    Hey Can, great review and summary as usual. I am going to add a bit to the CG loud experience since I have one of the earliest ones. Mine turned 2 years old last month and has over 20k miles on it with no CELs or any other issues.

    It never had any droning or buzzing but it does hum at low rpms in 6th gear. My only gripe was that it was too quiet inside the car. This problem has been completely solved since I added the headers and put some miles on them. I can now enjoy a much better sound from inside the car which I did not expect to be that significant.

    I think my car now has as perfect a sound as you can get from a TT and I do recommend the combination regardless of the questionable power gainsSmiley

    Re: My Audition of Cargraphic Exhaust

    Someone emailed me with a question about Cargraphic. Here is my (edited) response, basically my most recent "review" of the system. I have no affiliation with Cargraphic and couldn't care less if they are successful in prying another 5000 from a fellow enthusiast Smiley, just that when I have a hobby that is so much fun, I feel I must spread the "disease."

    >>>>
    I have Cargraphic. I ABSOLUTELY and MADLY am in love with the sound. I would recommend it without hesitation -- and I am a very difficult person when it comes to sound. No turbo exhaust will ever match a great NA sound like that Lambo howl (Oh Lord!), but this one comes as close as possible IMO. Even now at stop signs I step on the gas slightly just to hear the purr/bubbling. It is addicting -- there is no question about it, and it is one of the things I like the best about my car.
    Cargraphic is designed and made by RS Tuning, a very well respected name in Europe. These guys design exhaust for some of Europe Porsche racing teams. The racing pedigree is real and it's not a boutique company by any stretch of imagination. I feel no power loss in mine btw.
    Even though mine is the Loud Version, it is not loud at all, about the same as AWE. (They really should call it the Sport Version; I've talked to the US importer, RSS, about changing this somewhat juvenile name.) The only time I wish it were louder is if I were stuck in 3 hours of traffic after 10 hours of work (never happens, in other words; I have long hours but don't get stuck in LA traffic often).
    I would easily recommend the loud version because I hear people who pick the regular (Europe?) version could end up wishing for louder sound after a while. Keep in mind that when the windshield is up and at cruising speed, the sound proof of the Turbo is so good that you hardly hear anything loud. That's why I take my Turbo baby through tunnels and roll down the windows. Oh, and have another nutty enthusiast doing a fly-by at WOT, with you standing on the sidewalk, also works. LOL.

    Re: My Audition of Cargraphic Exhaust

    Mine is the middle loudness which is the max legal loudness here in the UK and I believe Germany. That's why they call the loudest one the 'export' version. Frankly though I don't think I'd want mine any louder. From outside the car apparently (in conjuction with my powerkit) it physically hurts peoples ears when reved in long tunnels! You can also hear my car from miles away when reved beyond 5000 rpm. From inside though with the windows closed it's actually quite quiet!
