One of the easiest ways to add some pizzazz to your car without breaking the bank is with an aftermarket exhaust system. Yes, you can go crazy and break the bank with a custom exhaust, but you don’t have to thanks to companies like Flowmaster, which have built an empire with bolt-on aftermarket exhausts that don’t require welding expertise or an ASE master mechanic certification. The latest offering from Flowmaster is its FlowFX cat-back system for the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 with the 5.3L L83 V8 engine. In other words, the system is for the K2 platform trucks, not the all-new T1 platform models.
Flowmaster says the FlowFX exhaust is easy to install using the trucks’ factory hanger locations. The system features three-inch, mandrel bent 409 stainless steel tubing paired with the FlowFX series straight-through performance muffler. To complete the look, Flowmaster adds a 4.5-inch black ceramic stainless steel tip. The exhaust note is definitely more noticeable and louder over the stock system, but not so much that it will compel the neighbors to call the cops on you. It’s also noticeable from within the truck, without being overbearing.
Besides the acoustic benefits, the Flowmaster exhaust for the Silverado and Sierra also increases performance, though only slightly. Horsepower and torque figures increase by about seven and eight, respectively. To top it all off, Flowmaster also offers a lifetime limited warranty.
It’s worth noting that this Flowmaster FlowFX cat-back exhaust system is much tamer than Flowmaster’s own Outlaw system that’s available for the 2019 Chevrolet Silverado and 2019 GMC Sierra; that exhaust sounds downright menacing, and the rumble alone would attract the eyeballs (and ire) of a bored police officer, while probably straining your relationship with your neighbors.
In any event, have a listen to the exhaust in action in the video for yourself by hitting the play button.

I'm sure if you could hear it over that tire sing it would sound "dope".
Pizza tastes dope
lol i asked before, but why all the Flowmaster 'articles's? Are they a backdoor sponsor?
Their exhaust kits aren't great and they seem to be the only exhaust company ever featured. If you're going to recommend a crappier product you should at least be getting paid for it like all the Instagram influenceers selling hair vitamins. FM exhaust is the hair vitamin of the car-world.
Andrew,
GM Authority has no "back door sponsors".
Not. A. Single. One. So your theory just does not line up with reality.
The reason that you may see coverage of Flowmaster-related content at one point or another is that FM makes something for pretty much every GM vehicle and produce videos to showcase their products with significant frequency, which we sometimes cover. Hence, they get into the news funnel that much more often than other purveyors of exhaust systems that make videos on a less frequent basis.
To further dispel your ridiculous conspiracy theory, the following links show GM Authority coverage of exhaust systems from manufacturers other than FM:
