991 Standard exhaust or Sport exhaust
#4
thanks... I have 997.2 and the exhaust noise is non-existant..... So, I guess the sport button in the cockpit is for sport exhaust? I read in one article about a membrane in the back that brings noise into the cabin?

There's no button on the standard exhaust that enhances noise. Only the sport exhaust. Also as per the Teamspeed review, with the sports exhaust, you get a resonance chamber with a membrane in between the cockpit and the engine, and when you select the sports exhaust button, the membrane vibrates in the resonance chamber and transmits some more of the engine and mechanical noise to the cockpit. Of course the entire exhaust system is changed as well, but that is just an added bonus.
