Sports Exhaust

Recommended Posts

2007 997-1 Carrera 4S : Does anyone know if switching the factory fitted sport exhaust on changes anything else on the car set up other than the exhaust note ( eg, engine mapping)?.

That's it. A whole big magilla over the sound. Sport Chrono and PASM change throttle mapping and damping. In a Turbo you also get more boost. It gets even better. In the 991 you can get the Sound Symposer. I think it opens a tube or something increasing the conduction of engine noise into the passenger compartment. No kidding. Next they will be stuffing microphones in cylinders 1 and 4 and wiring them to the cars sound system so you can sound like a Harley.

Yes, it just changes the sound with the aid of a solenoid and flapper valve. If you feel like changing the exhaust system go right ahead. The only down side will be a worthless switch in your center console. It won't affect anything else in the car. You can save a lot of weight in the back of the car by going to an aftermarket exhaust like Fabspeed and you'll sound sporty all the time.

If you change to 200 or even 100 cell cats, you will get less back pressure and increase horsepower as well...If you are just changing mufflers....Sound only :)

Makes a much bigger difference on 997 Turbo. I noticed it immediately on mine...Spools up quicker....Still on a NA car, flowing more exhaust quicker will enhance your performance
