Product Description

MBRP XP Series 4" Single Side Exit Cat-Back Exhaust System with a 5" Tip for F150s with a 3.5L EcoBoost Engine.

Give your 2011-2014 EcoBoost F150 a rich, mellow exhaust note with MBRP's XP Series Cat-back Exhaust System. An MBRP performance exhaust system is the starting point to getting the most from cold air intakes, tuners and other bolt-ons. The 4" cat-back looks great exiting the side of your truck just behind the passenger rear wheel with a single 5" mirror polished tip.

This exhaust spent countless hours on the dyno and hundreds of miles on the street and track to ensure the best performance possible. MBRP's cat-back was designed to maximize exhaust flow and minimize exhaust temperatures. This provides better fuel economy, performance and life expectancy. Seams are a major point of rust through with some budget systems but MBRP builds fully sealed tubing to add years to your system. Rugged 16 gauge T409 stainless steel construction can withstand whatever the road throws at it, whether it be salt, rocks, tar, grime, etc.

Features:
- 409 stainless steel construction
- Side exit
- 4" diameter tubing with a 5" polished tip
- Bullet style muffler
- Over 70% increased exhaust flow
- All necessary hardware and instructions included

The 3.5L EcoBoost engine makes minimal noise and if you want to increase the decibels and hear the turbo better, an MBRP cat-back exhaust system is the perfect choice. MBRP cat-backs pump up the decibels without making your ears ring. Exhaust notes are subtle and civilized during normal driving but seriously aggressive when you mash the gas. MBRP made sure their cat-back systems don't cause drone at highway speed so you can have a conversation without any trouble.

Minimal bends, smooth piping and high flow mufflers increase CFM and add a boost of horsepower. The stock F150 cat-back sees 477 CFM but MBRP's cat-back flows 877 CFM. With an exhaust flow increase of over 70%, you can expect great gains.

XP Series exhaust systems are designed and built to stand up to the harshest road conditions. Construction comes from T409 stainless steel, which is cheaper than the T304 stainless steel found in the Pro Series exhaust, but contains the same materials needed for long lasting and durable life. MBRP's XP Series exhaust is rugged and dependable, fighting off rust and corrosion.

Installation of the MBRP 4" Side Exit Cat-Back Exhaust System is relatively easy, needing a only a few hand tools to complete. You can have your 2011-2014 3.5L EcoBoost F150 sounding better in no time at all.

By Bill Tumas: Last time out with our EcoBoost F-150, we saw huge gains with the Dyno thanks to our Rev Auto 93 Octane Tune. Now that we have a good tune on the truck, we can start with the bolt-on modifications.

Like many of you, we're going to start the exhaust system. Today we're going to remove our stock Cat-Back and replace it with this 4-inch stainless steel Cat-Back from MBRP.

While it may look like it's designed for a diesel truck, MBRP builds this 4-inch system specifically for the 2011 through 2014 EcoBoost F-150's. It's a complete system that will work on both your regular cab all the way up to a super crew thanks to the pipes the include. It comes ready to install with this nice, polished, rolled tip.

We'll start out with a sound clip of the stock exhaust currently on our truck. You really hear more turbo than you actually hear exhaust system. It doesn't sound bad, but it definitely doesn't scream performance.

For this installation, you'll need a jack and jack stands or a lift, 1/2- inch ratchet, 3/8 ratchet, 15-mm deep socket, 15-mm socket, two 14-mm sockets, 10-mm socket, 8-mm Allen socket, swivel, rubber hammer and safety glasses.

Once you get the truck up in the air, you'll want to start by spraying some penetrating lubricant on the clamp here and also on the nuts here where the pipe connects to your wide pipe. We're going to start by loosening these 2 bolts here.

This side here, we don't want to take it all the way off. Take the bolt back just enough that it's loose and then we'll move the clamp. Now we can fully remove the front bolt. We'll spray the rubber insulators with a little bit of silicone spray to make them come off a little bit easier. The rest of the exhaust system from here all the way to the tailpipe is 1 piece. What that basically means is its heavy. It's a good time to get somebody to give you a hand because you have to work it off the 3 hangers to get it off the truck. We'll start by pulling the first off hanger where the flex pipe is up front. Then the whole system's got to go backwards to get it off the hangers. It comes out and you've got to sort of twist it. There we go. You want to use the supplied hardware to loosely connect your front pipe to your factory down pipe. You want to grab the clamp with the hanger, slide that over your front pipe and then into the rear of the first 2 insulators here.

Now we'll take the muffler, put 1 of our clamps on the front, put the rear mount into the factory rear insulator and then we'll connect that to our front pipe. We've found the easiest way to install the over-the-axle pipe is to remove this factory hanger, actually put it on the new pipe and then put the whole assembly into place. Before we install the over-the-axle pipe, we want to put a clamp on the back of the muffler. Now we can install the pipe. Again, make sure you install the factory hanger and insulator onto the pipe before you try to put it over. If not, it's going to kind of interfere with the spare tire and it's tough to get up in there. Now we can reinstall the original hanger and insulator. Now we can go back and tighten everything down once it's aligned properly. You want to make sure you have the rear pipe adjusted pretty much on the leaf spring and then we can tighten this one as well.

Our last part of the installation is to install the exhaust tip and line it up. Your installation is finished. Now we'll start it up with our MBRP exhaust installed. It sounds great, that nice, deep tone we've come to expect from MBRP but nice performance. You can hear the turbo a lot more. Now it sounds like a performance truck.

Our MBRP exhaust system fits well. The huge exhaust tip screams performance and it sounds killer on our EcoBoost. Installation should take you around an hour and you'll be back on the road in no time.
