Your 2005-2010 GT or 2007-2010 GT500 packs a thoroughbred of an engine. There is no need to bottle it up with restrictive, wimpy-sounding stock mufflers. Unleash the stallion within, with a Loud Mouth Rear-Section Exhaust System from SLP Performance Parts. This affordable, easy-to-install kit eliminates the factory mufflers entirely, drastically reducing back-pressure for enhanced power and a mind-blowing performance sound. Nothing else even comes close.
