SLP's Mustang Loud Mouth™ has always been the best-performing cat-back exhaust in the business. Now it's 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 resonators, the Mustang Loud Mouth system is compatible with our bullet-type Loud Mouth II Mufflers (#31064) and our traditional style PowerFlo Mufflers (#31065). They both offer flow and performance similar to our resonators but feature a ceramic-wrapped, perforated core that reduces high-frequency noise and in-car resonance for complete control over your Mustang's sound and performance characteristics.
NOTES: Includes Loud Mouth resonators. Loud Mouth II and PowerFlo mufflers sold separately.
