By: Dale Dotson | 03/14/2019 < Back to Motor Life Home

Flowmaster's American Thunder cat-back exhaust system for the 2019 Silverado Sierra 1500 (new body style) trucks with a 5.3L engine are perfect for the person looking for a moderately aggressive sound level outside the truck, with a moderate interior tone and all the performance benefits you would expect from Flowmaster. This emissions-legal bolt-on system fits all Crew Cab and Double Cab models with 5.5 and 6.5-ft long beds with factory dual exhaust option. Features include a flex joint, mandrel-bent 3.00-inch stainless steel tubing flowing into a Super 40 Series muffler for a deep powerful sound and added performance. The system exits the muffler through dual 2.50-inch mandrel bent stainless tailpipes which are finished off with quad 4.00-inch black ceramic coated stainless steel tips exiting in place of the factory bolt-on trim bezels. Designed for an easy fit, this system uses the factory hanger locations, includes detailed instructions and all necessary parts and hardware for an easy at home installation.
