No matter what you are looking for everyone is gonna have many different mixed opinions. At this point its up to you to decide what you plan on getting and let everyone know.

well ya 3" to 3" exit will have more flow but if the piping on ur exhaust (if u already bought an exhaust) is 2.5 it will just slow the flow down. personally i would get the 2.5" to 2.5" exit

And that's completely fine, i was just pointing out that at this point you are only gonna get the same answers over and over again.

I agree. A nice 2.5" magnaflow cat-back would go nice to compliment the new header and DP. Or which ever cat-back supplier you prefer, I personally like magnaflow. But i'll probably get GMPP because I can find it cheaper.

Agreed, maybe if you get the manifold, down pipe, and cat-back: all 2.5" the whole way. then I can see it coming close to 20hp gains, maybe.

what exhaust are you gonna get rockstar?
