Flowmaster American Thunder Cat-Back Exhaust System

Flowmaster went back to the drawing board when Ford released the 2013 Mustang GT to make one of the most brutal versions of their American Thunder series yet. This complete Cat-Back Exhaust Kit is purpose-built to make your 2013-2014 Mustang GT produce a massive roar like the muscle cars of yesteryear with a nice purr that you can hear and feel in your interior.

Quality Flowmaster Construction

The American Thunder Cat-Back Kit is manufactured out of high-quality 409 Stainless Steel formed into 3" diameter, mandrel-bent tubing. The smooth curves of the piping allow for more efficient exhaust outflow than stock crimped piping, giving you some slight power gains. The kickover tubes lead into a set of Flowmaster 60-Series mufflers that are topped off with aggressively-styled 4" polished tips.


This kit will not fit 2013 GT500 models. An American Thunder cat-back kit for 2011 to 2012 Mustang GT models is also available.
