F150 4.6L / 5.4L V8 Borla Single Exit Cat-back Exhaust (5.5ft Beds) 140136

Aggressive Sound, More Power, and Perfect Fitment

Borla is one of the biggest and most legendary names in the performance exhaust industry, and this single side exit cat-back kit for the 2004.5 to 2008 F150s gives your aggressive truck build the vicious roar that you've been waiting for in one of the highest-quality exhaust systems on the market. The Borla F150 single-exit kit has one exhaust tip that exits in the factory location behind your passenger side rear tire for a factory-style look. Borla's kit combines larger and more efficient exhaust tubing with a high-performance muffler to give your 4.6L or 5.4L V8 engine a brutal, throaty exhaust note when you punch the throttle while providing horsepower, torque, and fuel economy gains without the need for any tuning. The Borla kit was carefully designed for perfect fitment onto your truck, giving you excellent sound, power, and quality with absolutely no hassles.

Large-Diameter Tubing with Classic Borla Sound

Borla's exhaust kit is made out of 3" diameter tubing from your truck's mid-pipe all the way back to the system's oversized 4" rolled tip. The tubing is all mandrel-bent to ensure smooth routing and to reduce back pressure and restrictions over the factory crimped tubing. Borla's cat-back kit comes standard with an aggressive muffler design that provides your truck with a deep, throaty, and aggressive note when you're on the throttle, but has practically no drone or rasp at idle or cruising. Borla's F150 cat-back exhaust system is made out of high-quality 304 stainless steel that resists corrosion and discoloration in practically any climate and comes backed by a Borla Million-Mile warranty. Each one of these systems comes with a full set of installation hardware and detailed instructions.

Bed/Cab Fitment: this Borla cat-back exhaust kit only fits F150s built after June 2004 to 2008 with SuperCab or SuperCrew cabs with 5.5ft beds. All other F150s will require modifications to be made to this kit for proper fitment.
