Is anyone running MAC o/r Prochamber with Magnapack catback?

[y22kc]

Looking to do something different with my catback, was curious if anyone is running the Magnaflow magnapack catback with a MAC o/r Prochamber. I'm running MAC flowtech catback now, just wanting to try something different. Also considering Flowmaster original 40 series catback. Has anyone ever purchased this set: http://cgi.ebay.com/ebaymotors/ws/e...viewitem=&item=150291293595&_trksid=p3907.m32
