Factory Connect Only: this system will only fit factory cat-backs or aftermarket replacement cat-backs that keep the stock resonator assembly. It will not fit Stainless Works Performance Connect cat-back kits or aftermarket cat-backs that delete your factory resonator. Call Stage 3 directly at 1-877-578-2433 with any questions or concerns.
Wheelbase Fitment: this package is designed to fit F150s with 145" wheelbases out of the box. Trucks with 157" or 163" wheelbases will need to select Stainless Works Long Wheelbase Kit from our drop-down menu above for proper fitment.
This kit will require custom tuning for proper function, power gains, and to avoid engine damage.
