    Exhaust noise

    Hello to you all.  Recently I had my 997.1 Carrera S tuned. I installed X51 powerkit apart from the OEM sports exhaust due to the fact that it doesn't provide any hp gains. So I decided to go for an aftermarket complete sports exhaust system for beter performance. In more detail I added aftermarket headers, 200cpi race cats, mufflers and I combined those with X51 powerkit. On the dyno I got almost 410hp on the flywheel. No CEL lights, no problems at all. The car runs as if it was a factory job. I am really satisfied with the performance I got out of this whole kit, but I am dissapointed by the way the car sounds. It has become really noisy. The noise in the cabin when traveling is really really tiring and I have to say I begun to feel like installing a new exhaust. I contacted my tuner for that issue and he said it's hard to combine engine sound and performance at the same time according to people's needs and preferences. I don't really know what to do...Smiley. Some advice would be really apreciated. Also any of you had the same problem?


    Re: Exhaust noise

    Your tuner is right - if he muffles the sound more, then your hp gains will reduce.  However, you could ask him to muffle the sound - you might go down to at most 400bhp, but get a more pleasing sound to your ear.  But if he is just a supplier (and not a manufacturer), then he will not be able to do anything, as he will have only fitted a system manufactured by someone else.

    BTW I think Fabspeed does a switchable muffler system which would give you best of both worlds.  Check out their website - it's on the 2009 model page, but it should fit your car -ask them.

    When it comes to perfect sound and best of both worlds, nothing beats the exhaust system in a GranTurismo S. Smiley

    The V8 engine helps I think. You cannot do as much with a flat-6.

    Rossi, Reginos, Arshad, You're all right about your points. I totally agree about the V8 sound. I'll try to post a vid just to let you hear the exhaust idle and revving.

    P.S. If you ever drive through a tunnel in a motorway and all of a sudden you hear an airplane sound into the tunnel that can cause damage to your ears that would be me don't worry... Smiley
