A Key Part of That Kooks Exhaust Sound. With these big-bore 3” Cat-Back pipes hooked up to a Kooks H-Pipe or X-Pipe and suitable Kooks Headers, you get that fat, aggressive Kooks exhaust tone. Meaty, bold and powerful is the order of the day.

The Kooks Recipe for Success. The Kooks Full 3” Cat-Back Exhaust system works with the matching Kooks Headers and mid-pipe to free-up a huge path for exhaust gases. Flow-optimized race cats reduce emissions without hindering performance. With this system and some tuning, your Mustang will enjoy significant power gains.

Glorious Cat-Back Stainless System. This beautifully built 3-Inch Cat-Back Exhaust is designed to be installed along with Headers and a mid-pipe from Kooks. The system’s big bore, polished high-flow mufflers and dual polished 4” slash-cut tips, minimize restrictions for exhaust gases, so tuning produces better results.

Bolts In for Complete Kooks System. The Kooks Full Cat-Back exhaust makes use of matching Kooks Headers and mid-pipe to provide a complete Kooks high-flow system. It is engineered exactly to fit your Mustang.

Application. The Kooks Full 3-Inch Cat-Back Exhaust is designed for use with Mustang GT and GT500 models from the years 2005–2009.
