I've got a cherrybomb turbo on mine. I sounds pretty good. I dont have any clips of sound, but for $20 at autozone its not a bad deal. Maybe 2-3 extra mpg and it feels like it has a bit more in the low end range.
nobody wants a glasspack. i can only imagine how bad this sounds. maybe a thrush CVX (think loud raspy flowmaster) but not a true cherry bomb.
by the end of the month i'm going to have a random tech cat and 3" bullet on so i don't have too much room to talk about noise control.
