This MBRP exhaust system is great for those who own a 2005 - 2010 Ford Mustang GT 5.0 or a 2007 - 2010 Shelby GT500. Whether you're cruising on the highway or showing off at car meets, it'll make your vehicle stand out. It's perfect for car enthusiasts on a budget and people living in dry areas. The exhaust uses heavy - gauge aluminized steel tubing, and all the tubing is mandrel bent for better performance.
