This is the Magnaflow Competition Cat-Back Exhaust System that has been crafted to improve both the performance by adding more horsepower, more torque, while reducing turbo lag and improving throttle response. Magnaflow achieves the performance through a combination of smooth mandrel bends and larger piping diameter. Other benefits include improved gas mileage along with improvements in sound throughout the entire RPM range. This is a straight-through flow design that will flow enough power to work with future modifications that require a free flowing exhaust system to reach the full potential of those modifications.

The Magnaflow Cat-Back Exhaust System will come ready to install with exhaust hangers welded onto the OEM locations so that you don't have to perform further alterations to the body or chassis for fitment.
