super 44's stock cat, header, dumps off the muffler???

[1991notchbackLX]

I had the same headers, a prochamber and a Mac catback, and switched to an X pipe and dumped spintechs. Car made 272/316 with the Mac stuff and 258/295 with the spintech and X. I also did the wheels, tires, brakes etc... and it was different days.

that's good to know 25th, i was thinking of switching out my prochamber and spintechs to a VRS x-pipe and spintechs... i guess i'll be keeping the prochamber thanks!
