Product Description

The Kooks 11404200 Cat-Back Exhaust System is designed to dramatically improve the exhaust flow and sound of your 2011-2014 Mustang GT, 2011-2012 GT500, or 2012-2013 Boss 302. Built from premium 304 stainless steel with mandrel bends and polished oval race mufflers, this performance-oriented cat-back exhaust delivers a deeper, more aggressive tone while also enhancing throttle response and overall engine efficiency.

This system bolts directly to the OEM connection point on the factory exhaust using existing clamps (not included), providing a straightforward installation path. It is compatible with the factory exhaust system or can be paired with performance headers and mid-section X-pipes or H-pipes for further gains. The dual polished 4" slash-cut tips give a bold finished look and help project the exhaust's enhanced sound. Ideal for Mustang enthusiasts looking to combine performance, durability, and an aggressive exhaust note.
