FREE Shipping! Your ’05 GT packs a 300-horse thoroughbred of an engine. Why 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 backpressure for enhanced power and a mind-blowing performance sound. Nothing else even comes close! |
