SLPs Mustang LoudMouth has always been the best performing cat-back exhaust in the business. Now its the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, weve 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 youre done. No other system offers this level of performance and adaptability!
Along with the included resonators, the Mustang LoudMouth system is compatible with two all new SLP mufflers, the bullet-type LoudMouth II race unit (#31064) and the traditional-style PowerFlo (#31065). Buy all three for complete control over your Mustangs sound and performance characteristics.
