Years ago when I got my center dump pipes I also got a dyno sheet from PI that went with the pipes and of course I lost it. Something tells me it said 129hp which seems high. Anyone know where abouts Dave G. is now, the guy who designed these pipes. Everyone says that they don't make any power, mperformance has dyno numbers for slp, PI end dumps, psi stock blasters and they all make around the 130 hp. Someone on this site must have dynoed them.
