Large-Diameter Tubing for Big Gains

The only way you're going to get your 2011 to 2014 F150 EcoBoost sounding like a big, mean truck, is with a big, mean exhaust from the master craftsman over at MBRP. This 4" cat-back exhaust system is part of MBRP's XP-Series of stainless steel exhausts and will give your EcoBoost F150 a big bump in horsepower and torque along with an aggressive new exhaust note that is sure to catch everyone's attention. While much larger than your stock cat-back, the MBRP 4" XP-Series attaches to your truck's factory mid-pipe and is a direct bolt-on replacement for your stock cat-back kit that produces much more power and sound.

409 Stainless Steel Exhaust Tubing

MBRP constructs each of these EcoBoost exhaust systems our of 409 stainless steel to help the kit resist corrosion in a variety of climates. The system's 4" mandrel-bent tubing is paired up with an MBRP straight-through muffler that improves exhaust flow by up to 70% over your stock cat-back kit. The more efficient exhaust outflow and reduced pressure allow your truck to make excellent power and torque gains, especially when tuned or heavily modified. The MBRP cat-back system comes standard with a 4.5" polished tip that exits in the factory location for a more aggressive look than stock. Each kit comes with hardware and instructions for a quick, easy installation.

This cat-back exhaust kit deletes your factory resonator for a more aggressive tone.

Check out our install guide of this cat-back kit on our 2011 F150 EcoBoost Project Truck!

Not only does this product add a more aggressive look, it sounds great as well! Even with it being a v6, I was worried I wouldn't like the sound of it only due to the fact I have only owned v8 trucks, but I was wrong. Before I get in the truck, I stand behind the exhaust on cold start ups and just listen to the turbos spool as the rpms decrease. I highly recommend this product to anyone else with an Ecoboost F150. Took not even 30 min to install on a car lift. Very happy with what MBRP has produced for my truck.

Very easy to install, fits like a glove. Sounds very deep when you're on the gas and quiet at cruise.

this exhaust system sounds great , it didn't long to put it on either. my truck has a deep mellow tone to it and its not obnoxious either, it also added more hp and torque. i definitely recommend this to any one who's looking to buy a exhaust system for their ecoboost…

I am very pleased with this exhaust. The 5 inch black exhaust tip looks huge and gives the truck a real performance look. Has a great deep tone at start up and low RPMs. Higher RPMs does have a higher pitch, but I love the sound (Sounds a little different in person than in the above sound clips). Installation instructions provided were not very helpful, but CJ Pony Parts has a youtube video that made installation a breeze. Start to finish installation took about an hour on a car lift. (Fitting the pipe between rear leaf springs and spare tire heat shield can be a little tricky) To me, there seems to be a slight drone at cruising speed, but its not loud enough to be a bother to me. Great product from MBRP, and special thanks to Lou at Stage 3 for helping with shipping issues. I will definitely be buying more products from Stage 3.

2014 F150 Tremor FX4
I installed the MBRP 4" stainless 5238 yesterday. It installed fairly easily with the rear up on jack stands. It sounds amazing. Pretty sure I can feel the extra HP in the seat of my truck. two issues installing. first the rear hanger for the tailpipe with the pipe fully inserted into the muffler and the muffler pushed as far toward the cab as possible only penetrated through the rubber hanger 1/4" I felt that was not safe. I ended up cutting 1 1/4" off the muffler side of the tailpipe to allow for a full 1 1/2 penetration through the hanger. 2nd the band clamp did not secure the tailpipe into the muffler. at full clamp the band clamp would allow the pipe to rotate and have an obvious exhaust leak. I removed the spacer in the middle of the clamp which stopped the rotation but not the leak. I had and extra clamp in the kit, due to the 126" WB, but that still did not stop the leak. I will purchase some stainless muffler clamps and replace the band clamps. I love the sound, looks great, just two minor issues.

Super fast shipping that was free! Install was about two hours and had no problems. Most the install time was removing old exhaust system. Bottom line I was really surprised with increase in performance! Sounds amazing! Quite while idling and and light throttle then comes alive while accelerating. Should have done this sooner.

Everyone notices my truck when I roll around with this exhaust. It's not raspy or too loud. Great deep muffle and noticeable gains. I did have to cut the pipe extension to the recommended length since I have a 6.5 ft bed. Highly recommend doing it with a lift for an easier installation but I did it all on my driveway and took about 2 hours simply because some old bolts didn't comply. I can't say too much about other exhausts out there but I'm sure you will not be disappointed with this!! Great job MBRP and awesome customer service with stage3!!!

2014 f150 FX4 3.5L
The install took about an hour and all i did was lift the backend up and i could wiggle the stock exhaust right out from just disconnecting the midpipe. I personally love the sound and have gotten a lot of compliments so far in the 2 weeks of having it installed. If i had to say what it sounded like then i would say it sounds a little louder than a stock v8. It has a nice and deep rumble and stays deep throughout the rpm range. I do not believe this is too loud but i also do like louder exhausts so this is my personal experience. The trickiest part with the exhaust was lining up the muffler tip correctly. When i had the backend jacked up it was touching the leaf springs so i had to take the jack out to do the final adjustments and it hasnt rubbed yet. The last hanger at the outpipe is a little short, my hangar is actually in the rubber gromet by about a 1/4” so i think im guna have to go back under and re adjust it forward slightly or maybe even weld a little extension on it but its no big deal. The exhaust isnt going anywhere. I would definitely recommend this to others with the ecoboost. At idle it has a real deep rumble, it just doesnt have that loud growl of a v8 but i can live without that since i get to hear the turbos spooling

2013 F150 ecoboost FX4
instalation took about two hours in my garage with the pick up on jack stands. For the most part it was pretty easy to install, the tail pipe section was hard to get in place. could be because of doing it In the garage with very little room. Its a little too loud for me! If your building a race motor then this is a good one for that. My mpg seams to have dropped a little too. I would not recommend to a friend.

2014 fx4 f150
Install was pretty straight forward just had issues with rear hanger only about 1/4 inch thru. Ended up having to cut extension piece more as well as tail pipe into muffler end more to get hangers where I like em. Was having issue with pipes slowly slipping out and causing exhaust leaks so I just drilled holes in the hanger rods and installed hairpin clips to keep the pipes from moving. Only in really cold on first startup there are leaks but warm it's fine so I will be upgrading to band clamps soon. Otherwise minor issues looks and sounds great!

Just installed this exhaust and the install was quick and straight forward. I've only driven to work since the install and haven't checked for exhaust leaks yet. So far the exhaust sounds good. I'm happy with this purchase as well as the customer service that Stage 3 offers!
