Which is better h pipe or prochamber. Mac claims the prochamber is better and makes better power. H pipe is only $170 prochamber is 245$, for the difference in price is it really worth it?
 
yea i had a mac catback on my 03 gt when i had it, after a few months the welds broke, and my friends rotted out. i think this time around ill spend the few extra bucks and go magnaflow x pipe and catback.
