The most restrictive parts of the V8-powered F150s are their factory exhaust manifolds and the factory Y-pipe. To give your mighty F150 a big bump in output, you'll need a set of long tube headers and a corresponding shorty Y-pipe. F150 headers and Y-pipes help your truck get power by reducing back pressure and restrictions in your F150's exhaust system. Headers and Y-pipes also add a vicious sound to pretty much any F150. Just keep in mind, you'll need custom tuning for most long tube headers and aftermarket Y-pipes. To help make your truck really rip, take a look at our F150 Gears.
