Huge New Flowmaster Exhaust Sound with Improved Performance

No one does Mustang exhaust systems quite like Flowmaster, and their awesome American Thunder cat-back exhaust kit is just the thing your Fox Mustang needs to get an absolutely vicious tone along with a nice bump in performance. The American Thunder system brings a set of Flowmaster mufflers and more efficient exhaust tubing together into one kit to give your Mustang a deep, throaty tone just like a classic muscle car. The kit is an easy, direct bolt-on replacement for your stock cat-back kit for quick gains in sound and power.

Fits The Following Models:

  • 1999-2004 Ford Mustang GT
  • 2003-2004 Ford Mustang Mach 1

Flowmaster Super 44 Mufflers -- Aluminized

The American Thunder kit features two performance mufflers and tailpipes for both great sound and looks. The aggressive exhaust tone is brought to you by a pair of Flowmaster Super 44 mufflers which have a two-chamber design mated with Flowmaster's unique Delta Flow system for a deep, throaty, and noticeable roar. The kit's dual tailpipes use 16-gauge, 2.5" diameter, mandrel-bent tubing to promote efficient exhaust flow out of your Pony. This kit is manufactured right here in the USA and is backed with a Limited Lifetime Warranty.
