MAC Pro-Chamber H-Pipe 2V 3 Hts (For Shorty Headers) 1996-2001*The Pro-Chamber h-pipes go even further than traditional h-pipes to produce more torque & horsepower by merging exhaust pulses in one area. Merging of all exhaust gasses creates higher temperatures which creates a boost in exhaust velocity, plus forcing exhaust gas to see both outlets.
Placed Prochamber in place after long tube headers and high flow cats, then placed Flowmaster 10 Series mufflers down stream. Only the ProChamber can scavenge exhaust flow and provide that low growl beyond any other mid-pipe. Buy one, enjoy!
