Hey I’m Justin with AmericanMuscle.com and I’m taking a closer look at Flowmaster’s American Thunder series Cat-Back exhaust fitting the 2005-2010 Mustang GT, and GT 500. As you may or may not know, Flowmaster offers a wide variety of different mufflers, each with their own unique sound. In this case, the American Thunder centers around these two 60 series delta flow mufflers, which of course will still give you that iconic Flowmaster sound, but they’re not going to be as loud as Flowmaster’s 40 series mufflers. The American Thunder is constructed using durable 409 grade stainless steel, even including those 3 chambered 60 series mufflers. The system also features mandrel bends throughout, all exiting out these 4” polished tips, embossed with that Flowmaster logo. Getting this Cat-Back bolted up to your S197 is a very simple task, that should take you no more than 2 hours using basic hand tools. Now let’s hear how to Flowmaster American Thunder Cat-Back sounds compared to our factory exhaust.
