SLP Loud Mouth Exhaust System 1999-2004 Mustang GT/Mach 1
SLP's Mustang 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, re-tighten, and you're done. No other system offers this level of performance and adaptability!
Along with the included resonators, the Mustang Loud Mouth system is compatible with two all new SLP mufflers, the bullet-type Loud Mouth II® race unit (#31064) and the traditional-style PowerFlo® (#31065). Buy all three for complete control over your Mustang's sound and performance characteristics.
