1996-2004 V8 MUSTANG 2½ X-PIPE KIT


Direct Replacement high flow catted X-pipe

So whats the advantage of installing a Pypes 2½ high flow catted X-pipe over other available models?

Simply said, X-pipes create more power and torque than traditional H-pipe or the so called "prochamber" technology because they merge your exhaust pulses at the X. Traditional H-pipes loose this ability above 3000RPM and the H becomes non-functional part of the exhaust. The Pypes X-Pipe has been designed to fit both stock and shorty headers with an automatic or standard transmissions! The Pypes X-Pipe is complete with 02 sensor bungs and hardware for s quick trouble free installation.

Installation of this kit is quite simple includes all of the special parts needed and should take no more than 2 hours to complete.


NOTE: For 2004, 02 sensors are relocated. Extensions are required.
