SLP's Mustang Loud Mouth™ cat back exhaust system has always been the best-performing catback exhaust in the business. 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, re-tighten, and you're done. No other system offers this level of performance and adaptability!
Along with the included resonators, the Mustang SLP Loud Mouth™ catback exhaust system is compatible with SLP's bullet-type Loud Mouth II™ Mufflers (SLP-31064) and their traditional style PowerFlo™ Mufflers (SLP-31065). They both offer flow and performance similar to SLP's 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.
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.
