The perfect complement to the SLP long-tube headers and are an excellent complement to their "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. SLP gave them a three-piece design for versatility and easy installation; and you can get them with high-flow catalytic converters.

The future of performance X-pipe technology is here! Using groundbreaking design architecture first seen on SLP Mustang X-pipes, SLP Performance Parts® has developed a new line of modular X-pipes that can be quickly and easily reconfigured to fit changing performance, noise-level, and sound-quality requirements. Simply loosen a few band clamps, swap cat to no cats, retighten, and you're done. No other manufacturer offers this level of convenience and versatility!

SLP Performance X-pipe are built from aircraft-quality T-304 stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Coating techniques, such as aluminizing, can somewhat prolong the life of mild steel, but coatings suffer at the weld points. And, comparing aluminized steel to T-304 stainless steel is like comparing gold-plated metal to solid gold! T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion, and therefore the most desirable material for a long-lasting exhaust system.

SLP X-Pipe Full Assembly features:


• Modular design for easy interchangeability of cats to off-road race pipes
  
  
• Upgrades to SLP Long-Tube Headers without purchasing a new X-pipe
  
  
• Equipped with a true X-pipe crossover, not a poor-flowing clamshell imitation
  
  
• Constructed entirely from mandrel-bent stainless steel
  
  
• Complete with 02 extensions, clamps, nuts and bolts firs simple bolt on
