    Guaranteed Performance Gains. Compared with competing systems, Gibson Cat-Back Exhaust Systems are capable of creating more power from the 2000-4000 RPM range. This is thanks to the company's patented Superflow Mufflers and slip-fit connections. The end result is a 10-15 horsepower gain, along with an additional 15-20 ft/lbs of torque, leading to noticeable improvements in your truck's acceleration.

    A Loud and Aggressive Rumble. Thanks to the kit's larger diameter tubing, high-flow mufflers, and large tips, you can expect to hear a powerful exhaust rumble to match the gain in torque and horsepower. It also means you're sure to turn heads with a strong and sporty growl that's meant for the race track.

    Hassle-Free Mounting, No Welding Needed. Like all Gibson systems, this cat-back exhaust kit offers easy bolt-on attachment. Everything you need for a complete exhaust system upgrade is included, with no welding required for a full installation.
