Product Description

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

COBB's 3" Stainless Steel Dual Tip Cat-Back Exhaust System is a direct replacement system for your 2013-2016 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 2013-2016 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 or 2016 Focus ST from CJ Pony Parts today!

COBB Cat-Back Exhaust System Stainless Steel 3" Focus ST 2013-2016 is rated 4.363636363636363 out of 5 by 11.
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 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 4 out of 5 by from Nice look and sound I would give it 5 stars, but when I bolted everything up and used the cobb hangers, it was misaligned to the right, so much so that I had to have a muffler shop cut part of it and re fit it. It might have been caused by my lack of experience installing exhausts. Besides that, this exhaust is absolutely awesome. It gives a really nice growl at idle that isn't loud, but you can hear it. When you get on it it's awesome. It very easily passed the wife test.

Rated 4 out of 5 by from Quality product! CJ Pony Parts did a great job getting the exhaust to me. No delays etc. The exhaust it's self is very well built. Quality product. Was delivered in excellent condition. No dents, dings etc. The exhaust was very easy to install. All pieces fit together perfectly. The only difficult part was get the one section over the axle. I am very happy with the sound of this exhaust, low deep and smooth. Cobb builds very good products.

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 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.

Rated 3 out of 5 by from Looks good but very high drone Put this Cobb Catback on my Focus ST 2013. Installation very easy! Fitting is perfect! The sound on idle is perfect. But the incredible high drone when you hit the throttle from about 2500-3000 rpm is TOO much! You can hardly have a conversation. It's sounds like sitting inside a big subwoofer....
Date published: 2016-04-11
Rated 5 out of 5 by from Quality Another outstanding product by COBB. The catback exhaust has a deep tone to it that sounds perfect. Does get a bit of a drone from 2200-2600rpm under normal throttle, but not complaining :)

How, if at all, does this exhaust effect the vehicles warranty?

Hello, can I use this exhaust in Germany? Are there all papers for a German registration here? What is the price in euro, if I would buy this part this week? Have you any pictures es an example how it looks on a car? Thank you in advance.

Asked by: FocusSTturnier
It does not include European paper work. We will get an installed photo added.
