SLP's Mustang cat-backs have always been the best-performing cat-back exhaust in the business. Now there available for the 1986-93 Fox-Body Mustangs and most versatile, too! Using groundbreaking modular technology, 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 mufflers, the Mustang Loud Mouth II system is compatible with our Loud Mouth Shotgun Resonators (#31062) and our traditional style PowerFlo Mufflers (#31065). Switch muffler and resonators for complete control over your Mustang's sound and performance characteristics.
