Exhaust System Kit

The DynoMax Ultra Flo Welded Exhaust System Kit, part number 39539, is constructed from stainless steel with 100%-welded seams for maximum durability and a lifetime of performance. This cat-back system is specifically designed to fit 2019 and 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 5.3L engine and a 147.5-inch wheelbase. This pipe kit is intended for GAS Trucks only and provides the pure, unadulterated power of the Ultra Flo muffler. The system features mandrel-bent tubing for optimal exhaust flow. It is important to note that this kit does not fit trucks with factory dual inlet mufflers. Additionally, the DynoMax catalog indicates that some cat-back systems will not fit trucks with a rear stabilizer/sway bar. Ensure your vehicle configuration does not have these features to guarantee fitment.
