Chevrolet Silverado 1500 Performance Exhaust - Flowmaster Signature Series Cat-Back (2019-2026). Built for 5.3L trucks with factory dual exhaust, it delivers a deep, moderately aggressive tone with proven gains.

Designed for new-body Silverado 1500 Crew Cab and Double Cab models, this bolt-on system is constructed from brushed 304 stainless steel and TIG welded for durability and a clean look. A 3.00-inch inlet feeds a Signature Series straight-through muffler, then splits to dual 2.50-inch mandrel-bent tailpipes routed to clear the spare and tow hitch. The system exits through the factory bumper bezels to retain the stock dual-outlet appearance, uses factory hanger locations, and includes hardware and instructions for an at-home install. Dyno testing shows gains up to 21 hp and 26 lb-ft at the rear wheels. Fits 2WD and 4WD models with the 5.3L and factory dual tailpipes.
