SLP X-Pipe Full Assembly, 1999-04 4.6 SOHC/DOHC Mustang w/Cats.

The perfect complement to our "Loud Mouth" cat-back systems, these X-pipes use free-flowing mandrel-bent tubing and a genuine X crossover to provide a significant horsepower increase over the restrictive stock cat pipes. They're available with or without Catalytic converters and feature our exclusive three-piece design for unparalleled versatility and ease of installation.

NOTE: Includes detailed instructions and all required installation hardware. Photo may not show all included parts. 2004 SOHC applications require O2 Extension Harness (# M31037).

FEATURES:

• Exclusive three-piece modular design makes it possible to upgrade to SLP Long-Tube Headers without purchasing a new X-pipe
• Includes band clamps for easy interchangeability of cats and race pipes
• Equipped with a true X-pipe crossover, not a poor-flowing clamshell imitation
• Constructed entirely from mandrel-bent stainless steel
• Equipped with factory O2 bungs (where applicable)
• Fits 1999-2004 SOHC and 2001-2004 DOHC models
