Gibson 02-05 Chevrolet Silverado 2500 HD Base 6.0L 2.5in Cat-Back Dual Sport Exhaust - Stainless

This Gibson Dual Sport cat-back exhaust system is built with 2.5-inch stainless steel mandrel-bent tubing, designed to fit your 2001-2006 Chevrolet Silverado 2500 HD or 3500, and its GMC Sierra counterparts. The system exits behind the rear tire, giving your truck a distinct look that stands out whether you're on the street or heading off-road. It’s engineered to keep the exhaust clear of tow trailers, making it a practical choice for truck owners who haul loads.

The heart of this system is Gibson's Superflow™ muffler, which uses a baffled and chambered design without internal packing. This construction creates an authoritative, deep exhaust tone that’s aggressive outside but minimizes annoying drone inside the cab, so your conversations and music aren't drowned out. Dyno testing shows this system can add an average of 10-15 horsepower and 15-20 lb-ft of torque, offering a noticeable improvement in performance for your truck’s 6.0L engine.

Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all the necessary hardware, meaning no welding is required. The system is finished with polished stainless steel, slash-cut, clamp-on tips for a clean, professional look. Gibson backs this exhaust with a Lifetime Limited Warranty, giving you confidence in its long-term durability.
