| 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, retighten, 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.
