COBB 3" Stainless Steel Cat-Back Exhaust System with Dual 4" Tips for 2013, 2014, 2015, 2016, 2017 and 2018 Focus STs.

COBB's 3" Stainless Steel Dual Tip Cat-Back Exhaust System is a direct replacement system for your 2013-2018 Focus ST. The exhaust features full 304 stainless steel construction, custom inline mufflers and dual 4" double wall stainless steel tips. Installation of this system results in a drone-free and unique exhaust note.

Full stainless steel construction means the COBB cat-back holds up to the elements extremely well with high quality metal. Beautiful TIG welds seal all seams perfectly, resulting in zero exhaust leaks. CNC mandrel bent tubing creates the perfect fit every time for a no-hassle installation. COBB custom inline mufflers produce a sound unique to the COBB cat-back. Minimal restrictions increase exhaust velocity for the best bump in horsepower available. Dual 4" slash cut, double wall tips feature the COBB logo and look fantastic exiting the rear of your 2013-2018 Focus ST.

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).

Includes all necessary hardware and installation instructions.

Compliment this cat-back system with a COBB downpipe or upgrade to the full turbo-back exhaust system. Pair the exhaust with a COBB Accessport V3 Tuner for a fantastic bump in horsepower. COBB offers ready-to-run maps to maximize power made from their cat-back exhaust system.

Order a COBB 3" Stainless Steel Cat-Back Exhaust System with Dual 4" Tips for your 2013, 2014, 2015, 2016, 2017 or 2018 Focus ST from CJ Pony Parts today!

Rated 5 out of 5 by from Great sound, perfect fitment I bought this for my '13 ST3 for a little more "audible character" than it had from the factory. I've installed several other aftermarket catback exhausts from different manufacturers on previous vehicles I've owned, and this was by far the easiest, quickest, best fitting product I have ever used. The exhaust arrived much sooner than I expected - the website said it was a 2-3 week backordered item when I ordered, but it arrived on my doorstep less than a week after I ordered. The welds are beautiful, and the piping runs dead center down the stock exhaust channel. The tips were easy to center. I am definitely happy that I decided to go with Cobb!! I'll be back for a downpipe soon...

Rated 5 out of 5 by from Just right... The build quality of this exhaust is exemplary - beautiful TIG welds and fits perfectly. Almost too pretty to put under the car! Also appreciate the use of flanges instead of slip joints so that it won't get twisted out of shape later. The sound is perfect for me - loud enough when on boost and quiet otherwise. I drove it at 60, 70 and 80 mph and the "drone" on cruise was imperceptible - not sure what others were complaining about. If you tip into the throttle to accelerate then you can definitely hear the exhaust but it goes away as soon as your speed stabilizes. If this is too much "drone" then you should consider staying with the stock exhaust -it's very quiet.

Rated 5 out of 5 by from Piece o' Cake for 2015 ST Fits the 2015 ST and is an EZ Install. It takes longer to unpack it, get set up than it does to replace the exhaust. I didn't need any hanger pliers as my car is only a month old. I had to bend some heat shield out of the way (and back) when fitting the pipe over the rear axle. The actual work took less than 20 minutes. My 8-year old son helped my out with fitment and the awesome test drive!

Rated 5 out of 5 by from High quality! Sounds so good! Extremely high quality. Install was very simple on my 2016 ST. Nice deep tone on start up (wouldn't call it loud). Does NOT sound "ricey" at all. It is not obnoxious when driving through the neighborhood (so if you are worried about waking everyone up....fear not). Once you get out of the neighborhood and slam on that right pedal... well yea you are definitely going to hear it! In all seriousness this is a great sounding system. Again, I would not call this "obnoxious loud", but you it gets pretty loud when you want it to (in a good way). Very very little drone. On the highway, unless I am really accelerating hard, it's pretty quiet. In my opinion, this is one of the best sounding systems for this platform!

Rated 5 out of 5 by from Great quality, addicting sound! This exhaust system is by far the best quality system I have found for the Focus ST. Flange connections make sure the joints don't leak, full stainless steel, and a simple installation. When they say drone free, they really mean it! And when your on the throttle, your treated to an awesome low end tone! The sound is truly addicting, and very pleasing to your ears. I'd recommend this system to any ST owner, I truly believe its second to none. Well done Cobb, WELL done!

Rated 5 out of 5 by from Great opinion here Good: The build quality of this exhaust is by far the best I have ever seen. It is a shame that it will hardly ever be seen again. The welding is beautiful and almost crosses the boarder of craftsmanship into art. So, hats off to the guys at Cobb. Don't change anything in your quality department because it is really hard to find any flaws in your product. Bad: Please be aware that this is only my opinion. This flipping thing is way too loud. Between 2 & 3 in the rpm range it almost unbearable. I mean it fills the entire cab with ear rattling exhaust notes. Think about where you normally drive. Yep, between 2 & 3 in the rpm range. The solution to this problem is to be a man and tell yourself that this is what performance is, the sacrifice of silence and boredom for a few extra horsepower and the 3" mandrel bent piping is waiting for you to get your life together and give it 400+ hp that it desires. Would I recommend this exhaust? You're right I would! Because this is mans exhaust. Not a limp noodle can or an non-engineered straight pipe like the bottom dwellers buy because they're too impatient to save a little scratch and do it right. Buy this exhaust and you will be glad you did. It's only money after all....and manliness.

Rated 4 out of 5 by from Nice exhaust. Not raspy at all I really like the tone of the exhaust it's very deep. Videos definitely don't do it justice. It feels like it's loudest in the low rpms I was thrown off when I did my first pull I expected it to scream louder but the tone stayed the same. It's still a beautiful sounding exhaust it sounds good at idle and in some shifts you can hear it backfire. I haven't noticed any drone at 80mph but as soon as you want to speed up oh you can hear it. And get this thing in a tunnel and man does it sound beautiful. It's not the loudest exhaust but you can't go wrong with it. Over all no drone, loud enough, and adds SO MUCH character to the car.

Rated 4 out of 5 by from Makes car more special. I've had this cat back installed for about two weeks now and I have no complaints about its performance. It doesn't drone when cruising, it's deep and loud enough when you want it to be, but it won't annoy your neighbors when you're just driving around town. Great sound! Also, super high build quality. Zero fitment issues.

Asked by: Curryman59
Yes it should be the same. This is the exhaust only. I would suggest these hangers. https://www.cjponyparts.com/cobb-exhaust-hanger-polyurethane-kit-focus-st-2013-2018/p/591001/

Does this exhaust system come with its own hangers? Or should I go with the Cobb set? https://www.cjponyparts.com/cobb-exhaust-hanger-polyurethane-kit-focus-st-2013-2018/p/591001/

Asked by: Mpsquared
This does not come with hangers, you will need to reuse your existing hangers but we recommend the cobb hangers.
