Even though a single-exit cat-back kit isn't going to get you a much different look than your stock exhaust, sometimes that's exactly what's needed for a clean, but menacing 2011 to 2014 F150 EcoBoost build. MBRP's Single-Exit Cat-Back for the EcoBoost trucks is all about the sound. This kit really changes the tone and volume of your truck's exhaust for a much more aggressive and menacing tone. Like most single-exit systems, the 4" MBRP Cat-Back Kit is extremely easy to install, and simply drops right into place of the stock cat-back. The Kit's large 5" tip gives your truck just different enough of a look for a subtle upgrade over stock. We personally liked the sound, fit, and finish of this kit and we were more than happy to throw it on our 2011 F150 EcoBoost Project Truck.
The first step of our MBRP cat-back install was to grab all our gear and head down to Extreme Performance out in Goodyear, Arizona, so that our hands stayed clean while we photographed, filmed, and did everything but grueling manual labor. Both Kris and Aaron where helping us out and quickly got our EcoBoost truck up in the air to start removing our current exhaust kit. If you still have your stock cat-back system on your truck, go check out our Solo Mach-X Install guide for removal instructions.
Our first step for getting the MBRP single-exit kit onto our truck was to bolt the MBRP inlet tube onto our factory mid-pipe. Aaron got it on and then tightened down the supplied MBRP bolts.
With the inlet pipe in place, Aaron fit on a hangar clamp, slipped on our truck's forward exhaust mount, and then bolted the mount to our F150's frame rail.
Aaron then fit a clamp over the muffler inlet and then installed the muffler onto the inlet tube.
Once the muffler was in place, Kris fit on MBRP kit's over-axle tube and clamp into the muffler's outlet while making sure to slide its hangar into our truck's upper bed rail exhaust mount.
Kris then slipped on a clamp and installed the tailpipe assembly into the over-axle tube while sliding its hangar through our rear exhaust mount.
Once the tailpipe was more or less aligned where we needed it, Kris and Aaron wen through the the whole system and tightened down its clamps and our exhaust mounts.
Last, but certainly not least, Kris and Aaron double-checked tailpipe alignment before installing MBRP's tip and tightening it down.
With the tip on, our MBRP 4" Single-Exit Cat-Back Kit install was totally complete.
