Your 2011-2014 Mustang GT 5.0, 2012-2013 Boss 302, and 2011-2012 Shelby GT500 packs a thoroughbred of an engine, why bottle it up with restrictive, wimpy-sounding stock mufflers? Unleash the Pony within, with a Loud Mouth® Rear-Axle Back Exhaust System from SLP Performance Parts. This affordable, easy-to-install kit eliminates the factory mufflers entirely, drastically reducing backpressure for enhanced power and a mind-blowing performance sound. Nothing else even comes close! Combined with our 4" polished tips, you'll really feel and hear the difference!


Loud Mouth Axle-Back Exhaust System Features:
  • Mandrel-bent 2.5" tubing offers unbeatable flow characteristics
  • Significantly lighter than the OEM muffler assembly
  • Installs in around an hour
  • Constructed entirely from stainless steel
  • Hand-polished, 4" dual-wall tips provide a show-quality appearance
  • Emissions legal in all 50 states
  • Includes pre-welded hangers, detailed instructions, and all necessary installation hardware

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