MBRP Aluminized Series 3" Cat-Back Exhaust System for 2013, 2014, 2015, 2016, 2017 and 2018 Focus ST.

MBRP created the Aluminized Series cat-back for the cost conscious consumer. The Aluminized Series' low price is feasible due to the heavy gauge aluminized steel. Although the material used is different from other MBRP exhaust, the same high-quality design and craftsmanship is used. Seams are a major point of rust through with some budget systems but MBRP's fully sealed tubing adds years to your system. Expect high-performance gains from the Aluminized Series exhaust just like all MBRP products. The full 3" cat-back will produce a fantastic growl to set your Focus ST apart from others. Aluminized Series exhaust is suitable for areas with moderate environmental conditions.

Increase the output of your 2.0L Ecoboost engine by upgrading the Focus ST exhaust with a full 3" cat-back. The main focus of the Aluminized Series is to provide the cost conscious consumer with the same high-quality design and craftsmanship as MBRP's other systems but at a value price. Aluminized Series exhaust systems are made from 100% heavy gauge aluminized steel. Aluminized h-pipes are suitable for areas with moderate environmental conditions. For those needing an exhaust system that can handle the harshest road conditions, a step up to the XP Series would be in order. A polished mirror finish makes the underside of your Focus ST as attractive as the exterior. Polished dual wall T304 stainless steel tips exit the center of the rear bumper.

Please Note: Ford designed the 2015 Focus ST with four exhaust hangers but only added three on the factory exhaust system. All aftermarket exhaust systems are built to use that fourth exhaust hanger. CJ Pony Parts recommends the purchase of COBB’s Polyurethane Exhaust Hanger Kit (591001).

Each exhaust system is designed with the lowest bend degree angles and smooth mandrel bends so exhaust gasses have an easier exit path. This creates faster moving exhaust gasses, reduces exhaust gas temperatures and flows much better than the stock exhaust. Hundreds of test miles and hundreds of hours are invested into every MBRP system to provide you with the best sound and best performance improvement. Rigorous testing procedures ensure every component will fit as expected. MBRP designs their exhaust kits to be user-friendly with simple bolt-on installation. Includes installation instructions.

So what are you waiting for? Order an MBRP Aluminized Series 3" Cat-Back Exhaust System for your 2013, 2014, 2015, 2016, 2017 or 2018 Focus ST from CJ Pony Parts today!

If you've subscribed to our You Tube channel, you know we're big fans of the Focus ST. If we have one complaint it's that the factory exhaust system is a lot more rental car than performance car. Thankfully, it's an easy problem to fix. We've got Jesse here from MBRP who's going to give us a hand installing our 3-inch Cat-back on our 2013 Focus ST. All right, Jesse, tell us a little bit about this system you brought with you today.

Jesse: As you know, it's a Cat-back system, but it's quite a bit larger than a factory system. We're utilizing 3-inch mandrel bent tubing and a high flow muffler and a high flow resonator to dial in the sound specifically for this car. To speak on the mufflers, we actually built these from the ground up. We were going to use a unit off the shelf and nothing was really going to cut the mustard there so, we designed two things specifically for this application. What it did is allow us to really get the aggressive exhaust that the guys were wanting, without any of the cackle or the reverberations in the cab like people are used to.

Bill: I know you guys have made Focus exhaust for years now, long before the ST was even on the market. It's not an older focus muffler, it's built specifically for the turbo guys.

Jesse:It is built just for the Focus ST, yes.

Bill:And this is full stainless steel just like others?

Jesse:Yes, this particular unit is stainless steel. We have it available in two grades of stainless and aluminized, depending on your price point or where you live. If you live in Arizona, you really don't need a stainless exhaust system and we have an aluminized kit for that guy, which is quite a bit less expensive than the stainless stuff. Then we have a T304, which is our best grade of stainless and a T409 for the middle of the road.

Bill:No matter which kit, tips are always the same in the rolled full stainless. Are they 409?

Jesse:They're 304. All the tips, no matter what system it is, is going to be a 304 material grade. They're all the same, no matter what.

Bill:This kit comes with everything. It uses factory hangers, but new clamps, new gasket, new hardware, ready to go?

Jesse:It comes with everything you need to install it, but yeah everything that's needed to replace the factory stuff is in the box.

Bill:Cool, let's get started on the install.

Jesse:All right.

Bill:Before we get started we'll start with a quick sound clip of the factory exhaust. As you can see, just way to quiet for a car like this. For this installation you'll need jack and jack stands or lift, Sawzall, 3/8 ratchet, 15 mm socket, 14 mm socket, 10 mm socket, 8 mm Allen key, 15 mm wrench, 14 mm wrench, hanger removal tool, and safety glasses.

As always, the first step is to remove our old exhaust system. As you can see, it's got a huge factory muffler in the back and a rather large resonator up front. Not only is it restricting flow, it's also quite heavy. The first step is to remove this support bar located up here. To remove the stock exhaust system unfortunately you do have to cut it in half unless you want to remove your whole rear suspension. Make sure you go right behind the weld, usually this area here is the best place to cut.

Now, we're going to remove the stock rear muffler assembly. There are three hangers, one on this side, one here, and then a third one is hard to see, it's up over the axle. We'll remove these two nuts up here to separate our front pipe from our down pipe. Jesse, what's the first step in installing the new system?

Jesse:We're actually going to take this over-axle extension pipe and feed it from the rear of the vehicle toward the front up over this way using the factory hanger.

Bill:Okay. I've done this before with 2-1/2 inch systems, but this part is a little bit challenging. Is the 3-inch pretty tough to get through?

Jesse:You might find yourself massaging the heat shields a little bit as you work through, but it's not too bad. Just take your time. The next part we're going to do now is actually slide the tailpipe section in.

Bill:Okay. Again, all factory hangers?

Jesse: Yes sir.

Bill:I'm guessing don't tighten up anything yet, just get it all fitted into place and then we'll tighten it up?

Jesse:Just fit it into place, yeah. Next we have our extension pipe that bolts to the factory down pipe and a new high heat aluminum gasket. We're going to go ahead and install this. Now this only installs one way. It actually goes just slightly toward the passenger side.

Bill:Again, I'm assuming we'll get these hand tight for now?

Jesse:That is correct, yeah just hand tight.

Bill:Now we'll put the front muffler on next. You've got a clamp for the back then?

Jesse:I do.

Bill:I think there's only one more piece to do, you want to grab that? Put the clamp on that will connect it to our tailpipe. Now we start tightening everything down?

Jesse:Start tightening everything up. The last step we have is just to place the tips on here. We have a little bit of variation as far as personal preference or aesthetics. Personally I like things flush with the bumper, some people like them to stick out a little further. It's up to you. The basic thing is to make sure you have it centered in the opening of the bumper and after that you just tighten them down.

Bill:Cool, sounds good.

Jesse:We're actually going to tighten these one at a time starting with the left. That way you can actually get your tool in there to tighten it down.

Bill:And our last step is to reinstall the factory brace and your installation's finished. That's the kind of sound we're looking for. Nice deep tone, definitely after market, but not overly aggressive. Jesse, thanks for helping out with the install today. The system looks great and sounds great too.

Jesse:Yeah, we've put a lot of homework into this kit and developed it from the ground up. Not only does it look and perform better than stock, you also reduce the weight quite a bit.

Bill:Installation should only take you around an hour and a half and you'll be back on the road in no time.

Vehicle Fitment

This product will fit the following Focus years:

Rated 2 out of 5 by from POOR QUALITY CONTROL I order this for my 2014 Ford Focus because of the design for sound. I received the kit and unpacked it to install as I was installing I follow the instructions and started from the front to tighten everything down, the muffler would not tighten down all the way due to no slot in the exhaust to allow the pipe to seal. So exhaust leak. I had to cut thee slot in both ends of the muffler to allow the pipe to seal. MBRP told me only in the stainless kit is that done. Not good. I am still not done the tailpipe sizes were off and could not slide one of the exhaust tips on the pipe. Passenger side larger diameter then the driver. POOR QUAILTY CONTROL. so far no help for th Canadian Company.

Rated 5 out of 5 by from Best Exhaust On A Budget! I had already made the decision on the MBRP exhaust from reviews on different forums but was holding back do to cost. I found they made this aluminized version and went for it! I live in eastern NC and don't have to deal with much sea air or road salt so I didn't need the stainless steel setup. The only shortcoming here is the sleeved connections. I ended up cutting small slits in the ends of the parts that sleeve over to get a more snug connection.

Rated 5 out of 5 by from Dat' Sound Tho' I bought this about one month ago, and have loved every second of it. You really get a great turbo sound through the exhaust, and even better with its easy install. I gives a nice "Vroom" to the car with out sounding overly cheezy or "Ricy". It also feels significantly lighter on the car and by my guess takes off about 15-18 pounds. Hearing other Focus ST exhaust in person, this one easily takes the cake. Highly suggest you pick it up for a true America Hot Hatch Sound.

Rated 5 out of 5 by from Fantastic sound. Just installed my new MBRP exhaust and couldn't be any happier. Fantastic sound, improved throttle response. Haven't had the car on the dyno so can't verify a power increase, but car feels a little quicker. Not sure if that's because throttle feels more responsive or torque curve has changed slightly. Either way car feels a little quicker and the note is deep and booming for a 2.0L turbo. Also much lighter than stock system and looks way, way cooler. Installed in about an hour with basic tools.

Rated 5 out of 5 by from Not too obnoxious I’ve had it installed for a few days and I love it! Not too loud but just right, the main reason I went with MBRP was because I didn’t want drone and it was the best decision! Although if you want something crazy loud this might not be for you.

Rated 3 out of 5 by from Mbrp exhaust Like the exhaust but the fitment was pretty bad could not get two of the exhaust clamps to close had to take the exhaust off again from the down pipe back to the axel over section and weld it together for a seal.

Rated 5 out of 5 by from Great Sound! I replaced the stock exhaust on my Focus ST. The new sound is most impressive. I can't say that I have more power, but it certainly sounds like it! The big exhaust tips look good, too.

Will the ECU step in and limit power after this exhaust is installed? I've read about the ECU re-calibrating after mods. 

Asked by: Ben_E
No changes will happen after the installation of a cat-back.
