Description

Flowmaster's Signature Series Cat-back exhaust system for 2014-2019*(*Classic body 5.3L, 4wd w/143.5-inch wb) GM Silverado/Sierra 4.3L and 5.3L engines. This performance exhaust system fits both 2/4 Wheel drive models with 143.5 and 153-inch wheelbases and is manufactured from brushed 304 stainless steel for years of trouble-free service and highend good looks.

This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. Features include a 3.00-inch inlet pipe leading into a TIG welded 304 stainless steel Signature Series straight-through muffler for great sound and maximum performance. The single 3.00-inch mandrel-bent tailpipe exits out behind the rear passenger side tire and is finished off with a large 4.50-inch diameter PVD coated black chrome 304S stainless steel tip, giving your Silverado/Sierra that custom look that goes hand in hand with the deep performance sound of the Signature Series muffler. Max dyno gains of 9 hp and 10 lb-ft at the rear wheels. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes installation instructions and all necessary hardware.
