Install Guide: 2011-2014 F150 5.0L Borla S-Type Cat-Back Exhaust Kit on our 2012 FX4 Project Truck!

Posted by Jason Locke on 11/22/2013 to Install guides

The Borla S-Type – more commonly known as the "Stinger" – cat-back kit, is one of the most legendary exhaust systems of all time, and is by far and away Borla's most popular system across all of their vehicle offerings. Their S-Type kit for the 2011 to 2014 F150 5.0Ls maintains the system's flawless reputation and is the perfect middle ground between a hyper-aggressive and loud exhaust kit and a mellow, low tone. The Borla S-Type dual exhaust kit is practically silent at idle and quiet at cruising, but also give you an awesome and throaty roar as soon as step on the gas pedal. Even though the system has a dual-rear exit configuration, it's surprisingly easy to install, and our 2012 F150 5.0L FX4 Project Truck was ready to go make some noise in practically no time.

Step one of our Borla S-Type Cat-Back install was to head down to Extreme Performance out in Goodyear, Arizona, where Kris was ready and waiting to help us get our S-Type kit installed. Kris was fighting a chest cold, but he managed to tough it out through the installation of this exhaust kit, a Borla ATAK kit, and a Stainless Works Dual-Exit Cat-Back system. More on those later. We parked our truck on Extreme's lift, and Kris got right to work with our Borla Kit.

The stock cat-back kit is built to keep your truck quiet and features both a forward resonator and mid-mounted muffler. The first step of our cat-back installation was to hit all the piping connections with penetrating oil to help make Kris's life much easier.

After letting the penetrating oil do some work, Kris removed the bolts holding the resonator pipe to both the muffler's pipe and our F150's mid-pipe, before completely removing the whole assembly.

With the resonator pipe out, Kris maneuvered the muffler tube and over-axle pipe out of its hangars, over the axle, and out of our truck.

With the stock exhaust system completely removed, Kris attached the S-Type's connection tube to our FX4's factory mid-pipe using Borla's supplied (and very high-quality) bolts.

Once the mid-pipe connection tube was securely in place, Kris took Borla's hanger pipe and fit it through our truck's forward exhaust hangar and connected it into the mid-pipe connector. He then grabbed a clamp and let it hang for later. With dual exhaust kits, it's so much easier to get the tailpipes aligned with the exhaust system still loose.
