Gibson Performance Exhaust Cat-Back Dual Extreme Exhaust System, Stainless

A cat-back exhaust replaces the factory pipes, muffler and tips from the catalytic converter back. This is Gibson's Dual Extreme system in stainless steel, covering 2019-2025 5.3L trucks.

why this one — Gibson is the only one here that tells you where its claimed gains land: +10-15 hp and +15-20 lb-ft, optimized for 1,800-3,000 RPM, which is the range you tow and pull away from a light in. It is still a manufacturer claim rather than an independent dyno, and the $1,044 price was a sale off a $1,743 list, so confirm current pricing before you count on it.
