J.Seven:

Engine sound is one of the main pleasure a car can give, it ads soul to it. Reginos try to install the SW bypass mufler on your car, you´ll be surprise with the sound of it. I really find hard to be believe a 991 3.4L sounds better than my car. Anyway , I have a Cab which makes a considerable difference vs coupe. My car wIth hardtop on sounds indeed more muted even with PSE, but ever since I drop the SW bypass, even with hardtop you can hear the exhaust much better.

Thank you for your recommendation. I presume you replaced the central muffler with the SW pipes in the picture below?

I have the extended warranty and I'll have to check if this modification invalidates it.
