Product Details
This Gibson cat-back exhaust system, built with 3-inch mandrel-bent stainless steel tubing, is designed to improve the performance of your 1987-1989 Chevrolet or GMC R/V2500 Suburban equipped with the 5.7L engine. It exits behind the rear tire with a polished stainless steel slash-cut tip, giving your truck a more aggressive look. The system is engineered to provide noticeable gains in torque and horsepower, particularly in the low-end RPM range where it matters most for towing and hill climbing.
Inside, the system features a baffled and chambered Superflow™ muffler that is specifically tuned to produce an aggressive exhaust note outside the vehicle while keeping interior drone to a minimum. This means you get the performance benefits without the distracting noise on your daily drives or long hauls. The use of polished stainless steel for the tubing and tip not only looks good but also offers strong resistance to corrosion, ensuring this system lasts for years. Installation is straightforward, with all necessary hardware and factory-style hangers included for a hassle-free, bolt-on process that requires no welding.
This Gibson cat-back system is a solid option for owners looking to enhance their Suburban's power and sound. It's backed by a Lifetime Limited Warranty, giving you confidence in its durability and performance. If you're looking to get more out of your 5.7L engine for work or play, this exhaust system is a well-built choice.
