We recently detailed the new Flowmaster FlowFX cat-back exhaust system for the 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500 Crew Cab and Double Cab with the 5.3-liter engine. Now it’s time to take a look at the company’s American Thunder exhaust kit for the 2019 Silverado/Sierra 1500 Crew Cab and Double Cab with the 6.2-liter engine.
Flowmaster says its American Thunder exhaust kit for the latest generation of General Motors 1500 trucks is “perfect for the person looking for an aggressive sound level outside the truck, with a moderate interior tone.” The kit comes with a 3.5-inch stainless steel inlet tube that flows into a single muffler that then frays into dual 2.5-inch stainless steel tailpipes. Completing the kit are two sets of dual 4.0-inch black ceramic coated stainless steel exhaust tips, which exit in place of the factory bolt-on trim bezels and give the truck a tougher, more performance-oriented appearance.
The company also says this kit was designed for easy installation and comes with all the necessary parts, instructions and hardware for a straightforward DIY install. The kit will not fit the single cab work truck trims or any trucks with the factory single exhaust system. Again, it is designed for the 6.2-liter trucks with the Crew Cab or Double Cab body and 5.5-foot bed only.
You can listen to Flowmaster’s 2019 Chevrolet Silverado and 2019 GMC Sierra exhaust for yourself in the video above. The video includes sound clips taken from both inside the cabin and out of it, along with pre- and post-install dyno videos showing the potential power gains the exhaust kit can provide.
