Flowmaster American Thunder Catback Exhaust (11-12 GT)

Hey I’m Justin with AmericanMuscle.com, and I have with me FlowMaster’s American Thunder series Cat-back exhaust fitting all 2011 and newer Mustang GTs. The thunder you get from using this system comes from Flowmaster’s 60 series delta flow mufflers, which will still give you that classic muscle car sound, but will still be a bit milder than Flowmaster’s Outlaw series, or their Force 2 exhaust, which utilizes a more aggressive 40 series muffler. The American Thunder is a true cat back exhaust, meaning it eliminates your factory H-pipe utilizing 3” mandrel bent tubing all the way up to your factory cats. One thing we noticed with our mid pipe is it features a mini crossover, just to equalize your exhaust flow. Everything exits out these 60 series delta mufflers, and out these dual 4” hand polished tips. Getting the American Thunder bolted onto your ride is a straight forward affair which should take you no more than 2 hours using standard hand tools. Now let’s hear how Flowmaster’s American Thunder sounds compared to our factory exhaust.... HIDE
