Flowmaster American Thunder Quad Tip Axle-Back Exhaust w/ Ford Rear Lower Valance for Quad Tip Exhaust for all 2013-2014 GT/Boss 302 Mustangs.

Are you trying to achieve the look of a 2013-14 GT500 and get a louder and throatier exhaust note for your 2013-14 GT/Boss 302? Flowmaster set about re-engineering their American Thunder Axle-Backs. Flowmaster managed to deliver that classic and robust muscle car rumble while adding some style to the new Quad tips found on the 13-14 GT500. The kit is uniquely designed to provide the best performance possible while giving you the aggressive sound you crave. When coupled with the OEM Ford factory rear lower valance for the 2013-2014 GT500, you can get the look and the sound you desire.

The valance is a direct replacement for the 2013-2014 GT500 but can be installed on your 2013-2014 Mustang so you can install quad exhaust. Ford's GT500 valance can be installed directly onto 2013 Boss 302s and 2013-2014 California Specials without modification. However, the 2013-2014 V6 and GT factory rear bumper covers will need to be modified to accept the GT500 valance. V6 and GT Mustangs have markings on the backside of the bumper cover to show where to cut for this installation.

Features and Benefits:
- Unique styling of the 13-14 GT500
- Packaged together in one kit from CJ Pony Parts
- Stainless Steel Construction
- Easy Installation
- OEM fit and finish 

The Flowmaster American Thunder Quad Tip Axle-Back Exhaust system is constructed with mandrel bent 3" diameter 409S stainless steel tubing for maximum durability and includes two 3.5" diameter polished tips with a unique machined aluminum addition at the exhaust tip. Specially built Classic Two Chamber mufflers provide a very deep and aggressive sound level, and is suited to the enthusiast who wants a distinctive and powerful exhaust note. A true bolt-on that includes everything you need to easily install at home in your driveway with basic hand tools. As with all Flowmaster products, they are proudly built in the USA.

*2013-2014 V6 and GT Mustangs require cutting for installation of the quad tip rear lower valance.
