prochamber vs O/R H?

[rio95]

i have had the same problems with my bbk h pipe. They suck really bad. The cross member had to be welded at an angle, causing it to be 2 in. off the ground. It fits horrible and a couple of the hanger don't even go in the coupling. I am buying new exhaust tomorrow though.The prochamber will fit better, but will be a touch quieter.

Yeah had some fitment issues with my bbk o/r x pipe. They had to tweak it a little at the shop. But it sounds badass bolted to the flowmaster cat back! Other than the occasional rattle. Just remember one thing aftermarket stuff rarely bolts up like they claim in the adds!!!!!!!!!

well all of my mac stuff just bolted up like it was suppost to.
maybe im just lucky??

but the spark plug issue is a whole noher ball game!!

I got a shorty prochamber. The thing hits against my transmission pan so that I can't support it on the rubber gromets. Anyone else have this problem?

when i added a mac prochamber to my exsisting flowmaster exhaust the hole in the clamps didn't line up. i had to bend the studs that screw into the pc

I think thats one of my problems too. I go a flowmaster catback and the driver side holes weren't lining up. I only play around with it for a few minutes but at least I know now.
