SLP Axle-Back Exhaust, Loud Mouth™/Power-Flo™
 2005-09 Mustang GT/Shelby GT500

SLP Performance modular cat-back exhaust systems are built from aircraft-quality T-304 stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show.

Your mustang 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 fuel economy.

    FYI: *Sometime during the mid-production run on 2007 Mustangs, Ford realized that they were loosing money on the intricate metal/rubber exhaust hanger they designed for the 2005+ Mustangs. Thus they switched over to a cheaper rubber only hanger system to attach the factory exhaust. Unfortunately, this system will ONLY work with factory exhaust and will not allow for installation of aftermarket exhaust. Switching to the 2005 to mid-2007 style hangers solves this problem and will allow for installation of any 2005+ Exhaust System on late production 2007+.
