Ok thanks i would be keeping the same size diameter of exhaust pipe and keeping it single exiting out the back so would this be much of a gain.

Seen a difference right away. More throttle response and even more with CAI. Stock Y pipe, you can see the both 2 1/2 in pipes crushed in a 3 in pipe. Can you say castrated.lol. She needs air flow.
