FLOWMASTER MUFFLERS 817965 Features:
Flowmaster introduces our Outlaw Extreme stainless steel cat-back exhaust system for the 2019*-2023 (*2019 New Body Only) Chevrolet/GMC Silverado/Sierra 1500 with the 5.3L engine. This system uses an Outlaw series muffler for a deep powerful sound and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 15 hp and 20 lb.ft. at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.- Outlaw Series Performance Muffler Offers a Deep Powerful Sound and Increased Performance
