I finaly got around to swapping my BBK off road X pipe out for a MAC prochamber. First i must say i got rid of the bbk o/r X because it was crafted poorly and had fitment isssues with it, as well as leaks, but the x pipe did sound MEAN as HELL and that was coming from my boss who drives a WS6...anyway i put the Prochamber on which was a million times easier due to the three peice design it allowed to bolt up each flow pipe to each header (FRPP shorties) then i loosly fitted the back half and torqued everything down...i fired it up and....i was Impressed but depressed at the same time. It was about half as loud both at idle and high revs, which kinda depressed me....but on the other hand there were Zero leaks and it was a GOOD CLEAN and SMOOTH sound, no crackly decel noise, just good smooth revs which was real nice....keep in mind this is with FRPP's shortie headers and Mac flopaths, i thought it woulda been louder but i guess not.....anyway i was thinking about possibly swaping out for magnapaks, any input?
