Chevrolet Silverado 1500 Performance Exhaust - Flowmaster - Cat-Back, Flow FX Extreme - '19-'26. Built for 2019-2026 Chevrolet/GMC Silverado/Sierra 1500 5.3L (2019 new body), this stainless cat-back adds an aggressive-to-moderate tone with improved exhaust flow.

Crafted from 3.00-inch, 16-gauge mandrel-bent 409 stainless steel, the Flow FX Extreme pairs a Flow FX series muffler with a turndown dump immediately after the case, removing the over-axle tailpipe. This layout increases ground clearance and departure angle for off-road use while offering durable, corrosion-resistant construction. On the dyno, this system has shown gains of up to 15 hp and 20 lb-ft at the rear wheels. It reuses factory hanger locations, includes all required hardware, and is backed by Flowmaster's Lifetime Limited Warranty.
