Product Description

MBRP 3" XP Series Cat-Back Exhaust System for all 2013, 2014, 2015, 2016 and 2017 Focus STs.

Increase the output of your 2.0L EcoBoost engine by upgrading the Focus ST exhaust with a full 3" cat-back. Expect high-performance gains from the XP Series exhaust just like all MBRP products. This exhaust system is for the customer that needs a rugged exhaust system. The XP Series is meant to handle anything you can throw at it.

MBRP built this Focus ST cat-back to withstand everything from salt to rocks and tar to grime. High-quality construction comes from sixteen gauge T409 stainless steel. A polished mirror finish makes the underside of your 2013-2017 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.

MBRP Cat-Back Exhaust System XP Series 3" Focus ST 2013-2017 is rated 4.5 out of 5 by 21.
Rated 5 out of 5 by from Sound really nice I bought it 1 1/2 month ago, sounds really good exactly how I want it, look really good but the quality of the product is not that good, one of the end came with a bend that I get to bend it back and used it, a hole in the pipe, a dent in the muffler and one the the stud was too long and bump the hanger bracket at lot and finished cutting a little of the stud to fix that problem, I recommend to you if you gonna buy this product to get a set of Cobb polyurethane hanger to help the exhaust stay in place when you run for to long or hard and the heat make the factories hanger soft

Rated 5 out of 5 by from Very nice purchase.... I have a 2015 ST, Roush cold air intake, paired with this great MBRB exhaust make a lot of difference in an already intense car. The sound is really subtle on start up, and low rpm, deep though, definitely not stock. When you get the revs up, the car feels different than before, pulls harder, and sounds fantastic. Deep gets really deep, and fills the cockpit, with a lovely little burble, and crackle when you let off. Everything needed is in the box, had mine installed in 45 minutes for 50 bucks. When you look at what comes off, you won't believe the quality of the MBRB.

Rated 4 out of 5 by from So far, so good ! This is a great exhaust if you're looking for something not too loud, but is clearly not stock. It has nice, clear burbles and is loud when you want it to be. There's no drone on highways (thank god) and it has a great deep tone. I'm really happy with this purchase. The only annoying part is the installation. If you don't have a lift, what is supposed to be an hour and a half on installation turns into a day. Keep in mind to purchase some pb blaster to get the rusty bolts off of the old exhaust!

Rated 1 out of 5 by from Terrible quality control i just recieved this exaust in today and it had a terribly bend in one of the ends of the pipe and the piece that connects to the downpipe seems to be cocked to one side. i expected better from this company having spent $1500 before and having no problems. this didnt seem to be a shipping problem as the box wasnt damaged at all. hopefully i can make it all fit together tomorrow and get the bend out. I would also like to mention how terrible almost all of the welds were and the fact that there was flux and metal shaving all over the pipes.

Rated 5 out of 5 by from Great Sound Bought this last week. Had a local exhaust installer put it in, in under 1 hour for $80. The install was very straight forward. This sounds great! Happy with the purchase!

Rated 5 out of 5 by from Great Exhaust I read on the various ST forums that this was a "safe" exhaust choice. It has a deep, distinctly aftermarket sound, without it being overbearing. Fit and finish appears to be great (paired with the Cobb Poly Exhaust Hangers). I couldn't wait until Springs to put it on. Very happy with my MBRP exhaust.

Rated 5 out of 5 by from never knew a 2.0 L had balls ! this system rocks t man this car is almost complete. on heavy acceleration, this car sounds about as good as i have heard. it is not raspy at all. now she breathes. does not sound like a bean machine, 4" can on 1.5" pipe. keep up the great work.

Rated 4 out of 5 by from Great sounding exhaust! This Product is amazing. It gives my focus st a really nice low aggressive sound. Installation was a pain but most of the time it is. If you don't have a lift expect more then an hour for installation.

will this fit a Australian ford focus st? because Australian cars are right hand drive, cheers

Asked by: Logan95
We do not have a RHD ST to test these on and have not seen any feedback from someone that has fitted this kit. The manufacturer has not listed that either, but I can't see why it wouldn't work. Typically, everything is the same from the firewall back regardless of LHD or RHD.

Will your MBRP S4200409 fit a 2012 focus SEL?I know the rear lower fascia will need to be swapped out.

Asked by: xkrdreamer

Wondering what the difference is between the aluminized, xd, and pro series is.

Asked by: DavidjReed
The only difference is the material used to make the kit. Aluminized is aluminized steel, XP is 409 stainless Steel and PRO is 304 stainless steel. The 304 is going to look nicer than the 409 and the 409 is going to look better and not have surface rust like the aluminized.

MBRP Cat-Back Exhaust System XP Series 3" Focus ST 2013-2017 Video Transcript
By Bill Tumas: 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.
