    Awesome Look and Sound. The Gibson Dual Split Stainless Cat-Back Exhaust System has the aggressive look and sound that you’re looking for in a truck. The two tips exit out of the back and work well with most bumpers, roll pans and trailer hitches. Under towing conditions, you’ll experience even richer exhaust notes.

    More Than Just a Great Look. Backed by a lifetime-limited warranty, the Gibson Exhaust System decreases backpressure to produce even more torque and 15 to 20 more mph. It’ll handle all of your towing needs with ease and style with the dual polished stainless tips, and mandrel-bent tubing.

    Bolt-On Installation. This package includes all the necessary hardware for easy installation, and factory-style hangers for easy, bolt-on installation with professional-looking results. No welding is required.
