Built for maximum performance and ultimate sound, these header kits produced 27HP to the wheels un-tuned and over 50HP with tuning. Built using our step tube technology, we start with 1 3/4" primary tubes then step to 1 7/8" and terminate at a 3" collector with a power spike. We offer three Mid-Pipe choices: Catted to factory Cat-Back, Off-Road to factory Cat-Back and a full 3" to 3" Cat-Back.
