Gibson 14-18 GMC Sierra 1500 Base 5.3L 3in/2.25in Cat-Back Dual Sport Exhaust - Stainless

This Gibson Dual Sport cat-back exhaust system is built from polished stainless steel, featuring 3-inch main tubing that steps down to 2.25-inch for the rear exit. The system is designed to exit behind the rear tire, giving your truck a distinct look whether you're on the street or heading off-road. It's engineered to provide a powerful, deep exhaust tone without the annoying resonance inside the cab, making it comfortable for daily driving and towing.

The heart of this system is Gibson's Superflow muffler, which uses baffles and chambers instead of internal packing to create its aggressive sound. This design not only contributes to the authoritative tone but also helps to increase horsepower and torque, with dyno tests showing gains of 18-20 horsepower and 15-20 lb-ft of torque. The entire system is constructed from stainless steel with mandrel-bent tubing to ensure smooth exhaust flow and durability, and it comes with all the necessary hardware and factory-style hangers for a hassle-free, bolt-on installation that requires no welding.

Included with the system are polished stainless steel round slash-cut tips that clamp on, adding a clean, finished look. Gibson backs this exhaust with a Lifetime Limited Warranty, giving you confidence in its long-term performance and appearance.
