Joey just finished hes exhaust on his LS1 He did the same set up as I did on the LS2, Its a 3 inch going to a single 3 1/2 one resonator and a magnaflow 3 1/2 muffler.
I think they sound very nice!
We both are running mild cams and they have to do alot with the sound too.There is a video of my car running, but its inside a garage and sounds so loud,I should have some ouside video this weekend.
