Upgrading your F150's exhaust is your one-way ticket to a much more aggressive sound and more power. The stock cat-back systems on all F150s keeps these trucks pretty quiet and the factory manifolds and Y-pipes prevent your F150 from making all the horsepower and torque that it otherwise can. Luckily, there's plenty of aftermarket cat-backs, downpipes, and header systems for nearly every F150 out on the road. Also take a look at our F150 Intakes.
