Pypes 2005-08 Mustang Street-Legal X-pipe (replaces stock h-pipe).

The Mustang's oem cats are actually pretty good high flow cats. Rather than make you replace brand new ones, this specially made stainless X-pipe crossover can be added to your existing oem catted downpipes by cutting the downpipes in the appropriate spot and slipping this X-pipe over the existing pipes. Clamps and instructions are provided. Gain 8-12 HP and a unique sound!

**THIS IS A SPLICE IN X PIPE. CUSTOMER WILL HAVE TO CUT FACTORY H-PIPE.
