I just received the MAC hi flow catted prochamber pipe. Does anyone have this on a 2 chambered 40 series flows catback? I just wanna know what I can expect as far as performance and sound. Acceleration...etc.

 

nope so put it on and get some sound clips, the prochamber is supposed to sound real good

 

Where did you get the catted one from? Be sure to tell us how it sounds and get some clips of it!!!

 

It sounds good but good luck with the MAC staying together. Mac's quality really sucks.

 

I got the prochamber catted pipe from partshopper.com. It was here in 2 days.
