I am getting a corsa exhaust with a mac prochamber with the SC install. However I heard quite a few people say its a bit restrictive in terms of the design.

I spoke to MAC and they said it outflows the X and H pipe, and all around improves performance.

What does everyone think about this?

I think that all 3 (H,X,pc) are all going to be about the same in terms of your butt dyno....maybe the x a little less tq. at lower rpms, but what Im getting at is that I wouldnt dwell on it. PC sounds the best IMO. Alot of guys are boosted and still have sock exhaust. Dont dwell on it. Get the pc

I will let even know shortly...at least I hope so anyway!

Thanks for the reply - I didn't even see this reply at first due to email issues. Anyway, I hope it sounds nice with the Corsa Xtreme, and performs well.
