Gibson 99-01 Chevrolet Silverado 1500 Base 4.3L 2.5in Cat-Back Dual Extreme Exhaust - Aluminized

This Gibson Dual Extreme cat-back exhaust system is built with aluminized steel tubing, featuring 2.5-inch diameter pipes that are mandrel bent for smooth airflow. It's designed to replace your factory exhaust from the catalytic converter back, exiting behind the rear tires at an aggressive angle. The system includes a baffled/chambered muffler with no internal packing, which Gibson tunes for a mean performance sound and dyno-tested street performance gains, aiming for an average of 15-20 horsepower improvement.

The Superflow™ CFT muffler is engineered to provide an aggressive exhaust note while minimizing interior drone, a common concern with performance exhaust systems. Complementing the aluminized tubing are polished stainless steel slash-cut tips that clamp on for a clean finish. This kit comes with all the necessary hardware and factory-style hangers, making it a hassle-free bolt-on installation that requires no welding. It's a solid option if you're looking to give your 4.3L Silverado or Sierra a bolder look and a more powerful exhaust tone.

Gibson backs this exhaust system with a Lifetime Limited Warranty, reflecting their confidence in its construction and performance. If you're seeking an extreme exhaust upgrade for your 1999-2001 Chevrolet Silverado 1500 or GMC Sierra 1500, this system is designed to deliver a significant change in both sound and appearance.
