Product Description

SLP's Mustang Loud Mouth™ cat back exhaust system has always been the best-performing cat-back 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, retighten, and you're done. No other system offers this level of performance and adaptability!

Along with the included resonators, the Mustang SLP Loud Mouth™ cat back 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.

NOTES: Includes Loud Mouth™ resonators. Loud Mouth II™ and PowerFlo™ mufflers sold separately.

FEATURES:
- Includes SLP's infamous Loud Mouth™ resonators for virtually zero flow restriction and the meanest sound around
- Employs SLP's exclusive modular technology, making it possible to switch between resonator and muffler types in a matter of minutes
- Dyno-proven to outperform competitive resonator-type exhausts
- Engineered and built to OEM standards to ensure proper fit
- Constructed entirely from mandrel-bent 304 stainless steel
- Features show quality polished resonators and 3.5" double-wall tips with electro marked SLP logo
- Fits 1999, 2000, 2001, 2002, 2003, 2004 Ford Mustang 4.6L GT and Mach1
