The factory exhaust note on all of the 2009-2014 F150s isn't much more than a little kitten purr, but you can change that in an instant with any number of cat-back exhaust kits available here at Stage 3. If you want more power and torque, take a look at aftermarket EcoBoost Downpipes or F150 5.0L headers and mid-pipes. Just keep in mind that both downpipes and headers require custom tuning.
