I don't think you're going to see much of a performance improvement. It will get louder, not sure how the dinan mufflers will do, but the GT Haus exhaust systems sound pretty narly, of course different mufflers though too.

I have the vrsf 3.5 catback with a single outlet muffler delete just sitting in my basement if you want it. Loved the sound, the 3.5inch pipe gave it a completely different tone than dual 2.5 inch piping. My previous car was a mkiv r32 with stock exhaust and the resonator removed, and that car was louder.

see like i like how the dual exhaust looks i wanted to do a 3.5 dual straight pipe single look kind of boring to me..
