The turbos seem difficult in terms of exhaust note. Even with some after market exhausts I've heard. Better than stock but still lacks the Porsche grunt to my ears. Maybe I've haven't heard the right configuration yet.

This 2013 997.2 tt I heard the other day had a glorious deep rumble and sounded very cool IMO at idle and lower rpms. It did not hear it in the upper rev range. The owner swore up and down the car was all stock.

I really like the sound of my GTS at higher revs. I need to look and see if it has an X-Pipe or something aftermarket. I just like the way it sounds and don't care if it is stock or aftermarket enough to get down on the floor and look.

There are aftermarket valved exhaust options for thr turbo cars. Other than the coolant pipes, you also have to check that the cam gears have been addressed so they don't spin and get out of time.

I think you’re right. My 996 C4S with Fister mufflers had the best exhaust note of the three 911s that I’ve owned. My 991 turbo with FVD exhaust sounds better than the OE exhaust, but not as good as a normally aspirated car.

If you like it, my guess is that the center muffler has been replaced with one of a number of x-pipe options. With the OEM center muffler, the GTS is pretty quiet across the RPM range even with the standard PSE at loud mode. I have the Sharkwerks x-pipes and with the PSE in loud mode it really gets your attention beginning just under 4,000 rpm. Not obnoxiously or stupid fart can loud but just right for a 911 imo.

I had a 2006 C2S cab for 4 years. I sold it last May and bought a 2009 TT cab . I think the 2009TT is a major improvement over the C2S and I am very happy I did it.
