Who dunnit?
I'm seeing more exhaust systems designed for the 991 3.8 lately, aFe, Shark, Borla and the like.
Has anyone had a new system installed? If so, did you throw in a tune to maximize the performance?
It would be interesting to see the effects of both enhancements broken out individually and combined.

I did the SW side muffler delete, didn't like it.
Considering AWE that has the sound guarantee ,but if it prices out close to PSE I will just go with that. The AFE sounds intriguing if those hp gains are for real

I am in the market as well and have narrowed it down to the fabspeed x-pipe bypass, AWE switchpath, or the OEM PSE. Decisions, decisions....The AWE is almost as expensive as the PSE, but claims approximately 20 hp, the Fabspeed 16. That seems very optimistic. More power would be great, but I am primarily interested in a little more sound.
