COBB 3" to 2-1/2" Stainless Steel Downpipe with a Catalytic Converter for all 2014, 2015, 2016, 2017, 2018 and 2019 Fiesta STs.

Increase the exhaust flow from your 2014-2019 Fiesta ST's turbo with this new COBB 3” to 2-1/2" Stainless Steel Catted Downpipe (501200) ! This direct replacement downpipe for your 2014-2019 Fiesta ST is constructed completely of 304-stainless steel and is designed with a durable flex section and a high-flow catalytic converter to increase horsepower and torque production.

If you are tired of the factory downpipe on your 2014-2018 Fiesta ST stealing power away from your turbo, the free flowing catalytic converter on COBB's Stainless Steel Catted Downpipe allows for less restriction of exhaust flow. A solid CNC crafted construction gives you reliable durability and a substantially longer lifespan for the COBB 3” Stainless Steel Catted Downpipe. All of this, coupled with the expert-level TIG welded seams, gives you a well crafted piece of hardware that will perform greatly. The flex section allows for easy installation and gives the unit the ability to bend and move with the exhaust flow of your newer Fiesta ST.

COBB Downpipe Benefits and Features:
- Full 304 Stainless Steel Construction
- CNC Machined Turbo Flange
- 4" Flex Section for Easy Fitting
- 200 Cell Count Metal Spun Catalytic Converter
- 3" Stainless Steel Up to Catalytic Converter
- 2-1/2" Stainless Steel from Flex Section to Flange

The COBB cat-back exhaust system is a great complement for the catted downpipe. Make the most of the power COBB can provide by upgrading to a full turbo-back exhaust system that includes the downpipe and cat-back exhaust. Make a solid choice by pairing the exhaust with a new COBB Accessport V3 Tuner to experience a real increase the horsepower of your newer Fiesta ST can produce.

Rated 4 out of 5 by from Decent Performance Upgrade... Might need the catback too Installed this over the weekend. At this point I basically I have a full stage 3 package minus the cat-back exhaust. Overall I'm seeing about 50 ft-lbs of additional torque, less lag, and more consistent power. Would definitely recommend. Compared to stage 2, I am seeing the extra .5 psi of boost, but not much extra torque. Only 10 ft-lbs more. It is 20 degrees warmer then when I took the stage 2 numbers, so I suspect I will see better results as it cools. I don't know if the instructions where just wrong or if the FiST that Cobb tested was slightly different than mine, but the instructions for detaching the manifold heat shield where wrong. My heat shield has 2 parts. The portion over the exhaust manifold can be removed just like Cobb says, but there is another portion attached the stock down pipe that also has to be removed and cannot be reattached to the Cobb downpipe. The instructions don't mention this 2nd piece at all. I removed it and all seems well so far. Also we had to heat the downpipe with a torch to loosen the o2 sensors from the stock down-pipe. The instructions don't mention that but it worked and after 3 days the o2 sensors are still functioning.

will the down pipe also work with the flow master exhaust that I have installed? How much HP gain?

Asked by: DOUGIE15
Yes it will work. The HP gain will depend on the tune and any other mods that are done.

I have a mbrp cat back exhaust and I wanna go with the COBB Downpipe  can I do that ??????? also I got the stage 1 on my Fiesta st if I install the downpipe I have to go to stage 2 ??? Thanks 

Asked by: George780
Yes, that will work. You will not have to go stage 2, but I think you can as long as you have the intercooler I believe.

Does this downpipe work with the stock cat-back exhaust on the 2015 fiesta ST?

Asked by: AaronG
It will work, but it will limit your performance.

With the AccessPort, what sort of power increase can one expect along with the stainless cat back exhaust?

Asked by: John8508
That's entirely dependent on which tune you upload. Those power ratings are shown on our product page for the Accessport: http://www.cjponyparts.com/cobb-accessport-v3-2013-2014-focus-st-2014-2015-fiesta-st/p/AP3FOR001/
