Gibson 88-93 GMC C3500 Sierra 5.7L 3in Cat-Back Single Exhaust - Stainless

With this Gibson cat-back exhaust system, you're getting a complete package designed to bolt right onto your 1988-1993 Chevrolet or GMC C/K series truck. This system includes the exhaust tubing, a specially designed muffler, and polished stainless steel slash-cut tips, along with all the necessary hardware and factory-style hangers for a straightforward installation. It's built to exit behind the rear tire, offering a clean look and a sound that's noticeable without being overwhelming inside the cab.

This system is constructed from stainless steel, featuring mandrel-bent tubing for smooth airflow and a baffled/chambered muffler that Gibson calls their Superflow™ muffler. This design is tuned to deliver improved acceleration, better hill-climbing ability, and more power for towing and passing, with dyno tests showing the biggest gains in torque and horsepower between 1800 and 3000 RPM. You can expect an average increase of 10-15 horsepower and 15-20 lb-ft of torque. Despite its performance enhancements, Gibson has worked to minimize interior drone, so you get an aggressive sound outside without excessive noise inside.

Gibson backs this exhaust system with a Lifetime Limited Warranty, reflecting their confidence in the well-built stainless steel construction. The polished stainless steel tips add a nice finishing touch to the rear of your truck.
