Part #: slpM31007A

LoudMouth’s Mustang Cat-Back Exhaust Systems have always been the best performing exhaust systems in the business. Now they’re the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, we’ve developed a line of systems 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 exhaust offers this level of performance and adaptability!

Along with the included race mufflers, the
LoudMouth II® system is compatible with our original resonators (#31062) and our all new, straight-through type PowerFlo® traditional mufflers (#31065). Buy all three for complete control over your Mustang’s sound and performance characteristics.

NOTES: Includes SLP race mufflers. SLP resonators and PowerFlo traditional mufflers sold separately.
