The Sound That Started It All

American Thunder is the 'original' Flowmaster sound. In most cases a very aggressive sound level, American Thunder systems use various chambered mufflers to achieve the performance gains and aggressive sound that you want from your car or truck, inside and out. Available in stainless steel or economical aluminized steel, American Thunder systems are a great choice when you want to be heard.

2019 Chevrolet Silverado 1500 and GMC Sierra 1500 Crew Cab and Double Cab models with 6.2L V8 gas engine.
