STRATEGY In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the 03-04 Mustang COBRA. We have invested many hours evaluating and refining each of the Cobra products on our chassis “dyno”, to ensure that we could develop as much power as possible, as safely as possible. End result is our now available "Dyno Tuned Options". Our site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.

PYPES 409 STAINLESS 2½ crossover X-PIPE KITS
99-04 MUSTANG GT / Cobra / Mach-1

Direct Replacement high flow catted crossover X-pipe So what's the advantage of installing a Pypes 2½ high flow catted X-pipe over other available models? Simply said, crossover X-pipes create more power and torque than traditional H-pipe or the so called "pro chamber" technology. H-pipes no longer operate above 3000 rpm and become a non-functional component. Pypes crossover X-Pipe feature 2½ mandrel bent, 409 Stainless Steel pipe designed to fit in the stock location. Flanges, mounting hardware, O2 sensor rings, reinforcement plates, air tubes and ball flare connections are all standard features and are designed to fit both stock manifolds, short headers, automatic or standard transmission. Installation is quite simple and should take no more than 2 hours to complete.   Direct Replacement High-Flow catted, off-road crossover X-pipe Application / Description PYPES 409 STAINLESS 2½ CATTED crossover X-PIPE 99-04 Mustang V8 (all) 409 Stainless Steel 2½ mandrel bent pipe Stainless Premium substrate ceramic cats Fits automatic or standard transmission.
