I'm curious to see if the power gains come mostly from the "header/down pipe" and high flow cat replacement or the cat back replacement. I'm thinking that replacing the UR down pipe and high flow cat is where most of the gains are made. The stock set up looks a little restrictive at the top especially the down pipe and obviously the stock cat. Having said that I would still upgrade the full exhaust if I was doing anything.

just to let yall know,my tq/power from rv6 is still there and around 3k I can feel more power after installing 3inch cat from UR.

my only complaint is that the muffler doesn't sit dead center,is a little off to the right.
