Mustang SLP Loudmouth Exhaust (99-04 Cobra)

SLP's Cobra Loud Mouth has always been the best-performing cat-back exhaust in the business. Now it's the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, we've developed a system that can be quickly reconfigured to fit changing performance, noise-level, and sound-quality requirements. Simply loosen a few band clamps, swap muffler types, retighten, and you're done. No other system offers this level of performance and adaptability!

Features:

• Added a consistent 25 rwhp on SLP's stock '03 Cobra test car (modified vehicles will see considerably larger increases)
• Employs SLP's exclusive modular technology, making it possible to switch between muffler and resonator types in a matter of minutes
• Uses SLP's "Shotgun" race resonators for minimal flow restriction and the meanest sound around
• Dyno-proven to outflow competitive resonator-type exhausts
• Engineered and built to OEM standards to ensure proper fit
• Constructed entirely from mandrel-bent stainless steel
• Hand-polished, double-wall tips (3.5")--an SLP exclusive!
• For 1999-2004 4.6 Cobra models
