2013-2014 Mustang GT Flowmaster American Thunder Axle-Back (Stainless) 817588

Throaty, Aggressive Sound

While Ford did an excellent job of making the 2013 to 2014 Mustangs look aggressive and perform extraordinarily well, they definitely forgot to give them the vicious exhaust roar that they really deserve. The Flowmaster American Thunder Axle-Back kit corrects that issue and gives your Mustang GT a massive, throaty exhaust roar that instantly makes your Pony sound like an old-school muscle car straight out of the late '60s. The kit easily bolts on in place of your factory mufflers and exhaust tips for hassle-free gains in tone and volume.

Powerful Mufflers and Aggressive Tips

The kit is based around a pair of Flowmaster Super 44 performance mufflers that use a unique internal design to generate a deep tone and throaty exhaust note. Each muffler features two-chambers along with Flowmaster's Delta Flow technology that creates a great sound without reducing power output. The kit comes with a pair of 4" polished tips that are embossed with the Flowmaster logo. The kit is made out of 409S stainless steel and bolts right up to your factory kickover tubes. Flowmaster manufactures their American Thunder kits in the USA and backs them with a Limited Lifetime Warranty.
