Product Details
This Gibson cat-back exhaust system is built with 3-inch mandrel-bent stainless steel tubing, a design choice that helps maintain consistent pipe diameter for better exhaust flow. It's designed to bolt directly onto your 1975-1988 Chevrolet or GMC C/K/R/V series truck, including popular models like the 1980 GMC C1500 or the 1985 Chevrolet K10. The system exits behind the rear tire with polished stainless steel slash-cut tips, giving your truck a clean, finished look.
Inside the system, a baffled and chambered Superflow™ muffler works to reduce interior drone while still providing an aggressive exhaust note. Dyno testing shows this setup is optimized for low-end torque and horsepower gains, averaging an increase of 10-15 horsepower and 15-20 lb-ft of torque, which can make a notable difference when towing or climbing hills. Installation is straightforward thanks to the included hardware and factory-style hangers, meaning no welding is required.
This Gibson exhaust system is backed by a lifetime limited warranty, reflecting the durable stainless steel construction. It's a solid option if you're looking to improve your truck's performance and sound without excessive cabin noise.
