i thought it was all in my head first but after 2k+ miles driving with my SS exhaust, i can hear that it is now broken in. the sound changed, tunnels are incredible, and everything is smooth and perfect.
once your exhaust is broken in you can really notice the change in sound.
and yes the group buy will go on very soon. im going back to the dyno as i found the problem on why i lost power....vac line. thanks to logic i fixed it and used the ball bearing found in the golf tee post and reset the ecu by unplugging battery for 15 minutes, and yes i can now feel the power difference.
so my full review of sound clips, dynos, etc is comming as well as the group buy for all you e90 and e92 folks including quads
