Mustang MAC Pro Chamber H-Pipe 2-1/2 Auto (Long Tube Headers) 1979-1993
Part Number: PCA693
*79-85 requires double hump crossmember for dual exhaust installaion.
*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 all exhaust gasses creates highter temps, which creates a boost in exhaust velocity, plus forcing exhaust gas to see both outlets. These h-pipes are aluminized.
