Aftermarket exhaust information
What’s a good exhaust system for my 3.0i? I want it to be more growly at low and loud at high RPMs without being ricey or loud like a straight pipe. What experience have y’all had with this type of exhaust?

My system has a nice deep rumble and growls at higher rpm. Good amount of drone unfortunately around 3k RPM.
I have headers dual cats, 2 into 1 - 3” Supersprint pipe and Supersprint race muffler. I can get a sound byte if you want.

I have the same Supersprint setup, but with Aeroturbine resonators instead of cats. There's some drone, mostly due to the headers. I'd say drone is on par with my 996 Turbo with a Tubi exhaust, and about 25-50% of my Z4M's (both with catless headers and race cats, and one with Supersprint Race mufflers and the other with RE Diablos).
I posted a video on the dyno thread here.
