It’s no surprise then that General Motors offers a cat-back exhaust kit for the 2019 Silverado 6.2L, but you may not know all the details behind this factory-backed upgrade. GM recently released a short little video that features all the details of the kit and also some clips of a 2019 Chevrolet Silverado High Country revving and driving with the exhaust installed (embedded above), which be may of interest to any current or prospective 2019 Silverado 6.2L owners.
GM says the cat-back exhaust kit features “large front 3.5-inch and rear split 2.75-inch outer-diameter 304 stainless-steel pipes,” along with all the necessary hardware for installing it. The automaker claims a 40 percent reduction in engine back pressure at certain operating temperatures and up to a 13 hp improvement at 5,600 rpm and 8 lb-ft improvement at 4,100 rpm. These are SAE-rated figures as well, so the kit will provide a legitimate improvement in performance – not to mention the louder and more defined exhaust note.
Unlike some aftermarket exhausts, the factory kit is emissions legal in all 50 states and will not void GM’s New Vehicle Limited Warranty. The kit is also available for both short and long wheelbase versions of the Silverado, although the truck must be equipped with the optional 6.2L V8 engine. GM also offers such a kit for the 5.3L V8 Silverado, which is available in both single tip and dual exit variants.
Other performance upgrades available for the 2019 Silverado include a cold air intake for the 6.2L engine, front and rear brake upgrade kits, a range of Borla exhaust tips in different styles and a lifted suspension kit for 4×4 equipped models.
