GMC Sierra Performance Exhaust by Magnaflow
It's time to give your GMC Sierra a new soundtrack. Not from a booming speaker system, but from something that will make you want to turn the stereo off: With the Magnaflow Exhaust System, there's nothing like rocking and grooving to the true sound of your engine.
Of course, Magnaflow Exhaust Systems offer more than a throaty sound. Instant horsepower gains, abundant pulling torque, and a helping hand to improve your gas mileage are also on tap. Not to mention, the unbeatable performance looks running out the back end of your ride.
Magnaflow engineers their exhaust systems to bolt on easy, giving you more time to cruise. All pipes are mandrel-bent stainless steel tubing from the flanges to the tailpipes.
