Flowmaster Shows Off Its American Thunder Exhaust For Chevy Silverado, GMC Sierra: Video

Flowmaster has released its American Thunder series cat-back exhaust system for the Chevrolet Silverado/GMC Sierra equipped with the 6.2L EcoTec3 L86 V8. A system was also recently released for the LT1 V8-powered 2016 Camaro SS.

This Sierra/Silverado aftermarket exhaust system works great for these truck applications – it gives the Silverado/Sierra a more authoritative presence on the road with a nice throaty rumble at wide-open-throttle. While the tone is moderately aggressive, it isn’t overbearing, and that’s what we like most about it. The 3.5-inch tips add a nice touch, too.

The American Thunder exhaust system can be had for $739.97 with free shipping off of Flowmaster’s website. The 409S stainless steel system is crafter here in the states using patented Delta Flow technology, and is backed by a limited lifetime warranty.

A car-loving millennial. We Are!

  3. Meh, I clamped open my flapper, deleted my resonator and put in a magnaglow muffler. Sounds way better than this system and for $500 less.
