SLP's Mustang Cat-Backs have always been the best performing exhaust systems in the business. Now they're the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, we've developed a line of systems 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 exhaust offers this level of performance and adaptability!

Along with the included mufflers, the Mustang PowerFlo® system is compatible with our original Loud Mouth® resonators (#31062) and our all new, bullet-type Loud Mouth II® race mufflers (#31064). Buy all three for complete control over your Mustang's sound and performance characteristics.

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

  • Includes straight-through type PowerFlo mufflers for superior performance; minimal resonance; and a deep, rich tone
  • Employs SLP's exclusive modular technology, making it possible to switch between muffler and resonator types in a matter of minutes
  • Engineered and built to OEM standards to ensure proper fit
  • Constructed entirely from mandrel-bent stainless steel
  • Features show quality polished mufflers and 3.5" double-wall tips with electromarked SLP logo
  • For 1999-2004 GT and Mach I models

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
