Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2014-2019 Chevrolet/GMC Silverado/Sierra 1500 with the 4.3 or 5.3-liter engine. This system uses a Flow FX series muffler for an aggressive to moderate sound level 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 11 hp and 15 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. Fits 2014-2019 Chevrolet/GMC Silverado/Sierra 1500 4.3L/5.3L, Flow FX Extreme 3.00-inch Stainless Steel Cat-Back Exhaust System
