3-Inch Cat-Back Exhaust System w/ 3.5-Inch Tip

The Gibson Performance Exhaust 315571 is a top-performing cat-back exhaust system engineered to deliver an ultimate boost in acceleration, towing, hill climbing, and passing power for 1988-1993 Chevrolet and GMC 1500 Pickup trucks equipped with 5.7L or 7.4L engines. This system is constructed from heavy-duty Aluminized Steel with 3-inch diameter, mandrel-bent tubing. At its core is the Gibson Superflow Muffler, featuring a baffled and chambered design that operates without internal packing. The exhaust system exits behind the rear tire and is finished with a 3.50-inch polished T304 stainless steel tip. This tip features a round slash-cut design and a clamp-on installation for a clean, stealthy look. Dyno testing has demonstrated significant performance gains for this system, showing an increase of 10-15 horsepower and 15-20 lb-ft of torque, primarily in the 1800-3000 RPM range. This translates to tangible improvements in low-end torque and overall horsepower that drivers can feel. The system also features a slip connection to the converter, simplifying the connection process. Gibson backs this American-made product with a Lifetime Limited Warranty.
