Cervini's GT500 Side Exhaust Kit (8036) - 2007-2009 Mustang GT500
Give your 2007-2009 Shelby GT500 an unmistakable muscle car presence with the Cervini's GT500 Side Exhaust Kit. Combining aggressive styling, premium stainless steel construction, and proven performance gains, this complete side exhaust package transforms both the appearance and sound of your Mustang.
Designed specifically for the S197 GT500 platform, this system relocates the exhaust outlets to the sides of the vehicle, creating a classic performance-inspired appearance while improving exhaust flow. The side exhaust design reduces restrictions found in traditional rear-exit systems, helping your supercharged Mustang breathe more efficiently.
At the heart of the system are Magna Force 304 stainless steel mufflers featuring a straight-through race-inspired design with a 95% unrestricted flow path. This high-flow configuration has been dyno proven to deliver gains of 8-10 horsepower while producing a deeper, more aggressive exhaust tone.
The kit includes durable side skirts, stainless steel dual side exhaust components, and rear valance covers that conceal the factory rear exhaust openings for a clean, finished appearance. Rear valance covers install using OEM mounting locations without cutting or drilling, making installation significantly easier than many custom side exhaust conversions.
Constructed from premium mandrel-bent stainless steel tubing and backed by Cervini's limited lifetime warranty, this side exhaust system delivers the quality, performance, and styling expected from one of the industry's most respected Mustang manufacturers.
