Part Number: PC9900
MAC Off-Road Pro Chamber H-Pipe for 1999 4.6L 2V/4V Mustangs with Stock or Shorty Style Headers.
This Pro-Chamber H-pipe is made from uncoated, aluminized mandrel bent 16 gauge tubing, and merges exhaust pulses to create higher temperatures. The result is a boost in exhaust velocity, forcing exhaust to both outlets.
