Prochamber Exhaust
 

I have read the reviews of the Prochamber on Stangnet and none of them talk about ground clearance issues. Have any of you (that had had or seen a Prochamber setup) noticed any clearance problems. A guy at the track last night said that he had to take his off because it would drag on high spots (driveways, speed bumps, etc.). Any advice would help me. I prefer the Prochamber but will settle for an off-road H.

Thanks...

Not sure about clearance but i know they are loud as hell. A real hollow sound on top of the muffler growl. My friend pitched his due to the annoyingly loud sound, not much difference in HP gains either. His never dragged but his car wasn't lowered so that could make a difference.

Your buddies car was probably just too low as it was. I have a buddy with long tubes that couldn't fit a D sized battery under them.
For a moderately lowered car however the ProChamber is fine. As for the HP gain I felt a difference between the ProChamber and a Flowtec X Pipe.
