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.

PYPES STAINLESS 2½ VIOLATOR SERIES CAT-BACK
100% Stainless Direct Replacement Cat-back Exhaust Kits

25+ rear wheel HP

What's the secret to the fast-rising popularity of Pypes exhaust systems and components?

Is it some proprietary design that allows a Pypes exhaust system to reduce restriction and increase power? Is it a highly confidential equation that allows Pypes' mufflers to produce just the right combination of sound and performance? Maybe.

We think the real secret behind Pypes Performance Exhaust's success is that their systems and components offer all the benefits of typical stainless steel systems. They resist corrosive gasses better than systems made from aluminized steel or other materials, so they maintain their looks and last longer.

Simply Said; Pypes combines those benefits with a surprisingly affordable price and a lifetime warranty to make them the ultimate in exhaust system value.
