    exhausts and Frankfurt show

    I'm looking at several exhausts, and Cargraphic seems the best. Any users who could give me any comments? I'm also going to the Frankfurt show. I've been twice, but would gladly appreciate any advice, especially as to tuners (there never seem to be too many mechanical tuners, mostly cosmetics).

    Someone on another board made some extensive testing. You can download the results from http://www.rennlist.com/imagineauto/

    Someone? You mean a company, somebody selling stuff.
    But even if we suppose these tests are accurate and not biased in any way, I highly doubt the results.
    Why? We just talked to a well known Porsche Tuner a few days ago and the main discussion theme was dyno testing.
    Fact: most dyno testing results have an error of at least 5 to max. 10%, even if done properly. Only if you take out the engine and do a back to back testing, you might get pretty accurate results. This is actually what I heard from many sources who are into serious engine tuning, including exhaust setups.

    Regarding a "good" exhaust for the Turbo/GT2: testing is a vital thing. Forget about systems who use the original exhaust and just "modify" the content. These systems usually are very loud...but that's it.
    A good advise would be to use an exhaust from a well known tuner who also offers power kits at the same time. Usually these tuners also tested the exhaust on the dyno (engine ONLY!) to adapt all mods one to each other.
    Another hint: the cheaper the exhaust, the more careful people should be. A good aftermarket exhaust with high quality material/housing and high quality high flow catalytic converters can't be bought for 1500 USD only. Bear in mind that serious development of such exhausts isn't cheap and the material used should be not only reliable with the stock power but with substantial power upgrades too.

    I know that my warnings are usually useless and people do not listen but let me put it this way: you put big money in a Porsche 996TT/GT2 and now you want to save a few bucks on a very important part of the engine setup? YOU tell me.

    Re: exhausts and Frankfurt show

    The people who made this test deserve credit, even if they are sellers. They had perform a very rare and unique kind of test. Must be hard to put together so many aftermarket exhaust and perform a test like this on a 996TT, it's a hell of work and they seemed to be fair on their analysis/comments. But the results of those tests are some how unrealistic. There were exhaust making 40 and even 50Hp more than the stock unit at high rpms. There's no way an exhaust could give so many HP.

    I also find strange to see several discussions regarding that test of every other Porsche forum and not here
    I still find this to be the best Porsche forum

    Christian, the tests were performed by Stephen, of Imagine Auto. While some tests results seem to be anomalous, especially when it comes to Ruf, Stephen did a fair comparison. Now, you have to take into account that all the tests were performed on his car, equipped with the EVO MS Stage IV 600 HP engine. The exhausts may perform very differently, once attached to a different engine. I myself would buy a Europipe exhaust, if I had a Turbo to modify. Europipe website
    That's what cjv used for his "Turbo/GT2S/CJV S-CAR-GO"

    My favorite is Phoenix, a UK based manufacturer who does the Cargraphic exhaust and a lot of work for GT3 Cup/Race cars but anyway, I'm not here to advertise any brand.
    The main point is (and you got it 100% right): with a modified ECU, exhaust test results are already completely different than with a stock engine.
    This is why I have the only good advise for people interested in a good exhaust for their 996TT/GT2: get the whole package from ONE source or if you don't want to do ECU/engine mods, go for a well known tuner/manufacturer whose offer doesn't sound to be too good to be true.
    I saw claims of a 35-50 HP gain with exhaust only...FORGET about it. I saw offers in the 1000-1500 USD range, forget about it.

    Or to make it short (I hate repeating myself ): owners should go to their Porsche dealer and ask how much a new engine on the 996TT or GT2 costs. After hearing the price tag, a lot of owners will go for good quality...or leave the car stock.
