Product Description

SLP's Mustang Loud Mouth exhaust system has always been the best-performing catback exhaust in the business. Now it's available for the 1986-93 Fox-Body Mustangs including 1986 GT's & 1993 Cobra's and most versatile, too! Using groundbreaking modular technology, SLP has 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!

SLP Loud Mouth Resonators
SLP's Loud Mouth™ "Shotgun" resonators offer wide open exhaust flow and race-ready performance with an ultra aggressive sound too match. Standard equipment on SLP Loud Mouth™ exhaust systems, each resonator boasts its own unique tone and flow characteristics. They are constructed from hand-polished stainless steel and embossed with the classic SLP logo.

Along with the included resonators, the Mustang Loud Mouth system is compatible with SLP bullet-type Loud Mouth II Mufflers (#31064) and SLP traditional style PowerFlo Mufflers (#31065). They both offer flow and performance similar to SLP 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.

- Includes SLP's infamous Loud Mouth resonators for virtually zero flow restriction and the meanest sound around
