This system is exactly what the truck needed. Woke it right up! Nice rumble and not too loud. Boosted the power. Easy install and fitment is perfect. Great job flowmaster!

I installed this product on a 2019 GMC Sierra crew cab. Every bend was spot on…hangers lined up… I did have to shorten the pipe from the cat to the muffler and install it backwards from the instructions to accommodate the factory ‘tips’ but it installed easily and sounds like this truck should.
