Ford Turboback Exhaust System Fiesta ST 2014-2019 is rated 4.8 out of 5 by 31.
Rated 5 out of 5 by from Best exhaust out there This CBE sounds amazing. It is very quiet when cruising or just driving around conservatively, but it lets out an amazing sound as soon as you start to accelerate a bit hard. It's a perfect balance considering that I didn't want my car to be howling and roaring while driving around parking lots or school zones. Highly recommend it. The only down side is that this is one of the more expensive CBE out there for the FiST, but definitely buy it if you can afford it

Rated 5 out of 5 by from Improves Throttle Response I am baffled that no review mentions the improved throttle response. Yeah the sound is great, and when you have your windows up its almost like stock. But when you come off of power in high revs, there is no jerking. With the stock car there is too much back pressure. This catback makes the throttle MUCH SMOOTHER. For the stock car, it almost feels like it has a massive flywheel. Takes awhile for the revs to drop. I guess less back pressure fixes that. Im surprised Cobb NEVER mentioned this. I feel like its a great selling point. I was go giddy when I started to do some spirited driving. Also it smells like burning paper for awhile. This is my first Cat-back system, had to look online to make sure something wasn't wrong.

Rated 5 out of 5 by from Sounds great when you want, but not too loud when cruising As you read this, bear in mind I upgraded from stage 1 to stage 2 + the cobb downpipe first. Then I added the cat back exhaust a few months later to complete stage 3. Also, I have flashed the ECU with the Cobb AccessPort to re-tune engine for each hardware upgrade. WITHOUT RE-TUNING YOU WILL NOTICE VIRTUALLY NO GAINS Performance: With stage 2 + down pipe I got significantly improved torque. I measured the estimated torque on the AP before and after and the gains were right inline with Cobb's numbers. Adding the cat back added a good amount more power and really helped with turbo lag. With the cat back I also feel more power on the top end making the engine feel like it continues to produce more power throughout the RPM band instead of plateauing at 4000 RPMs. I haven't put it on the dyno, and I did stage 2 + downpipe in the winter and then added the catback in the May. With the huge temperature difference in Chicago I don't have any reliable numbers on the performance gains, but based on feel alone I would say what Cobb publishes feels accurate for what its worth. Also, I recently uninstalled and re-flashed the stock ECU before taking my car into Ford and was shocked just how much less power it has at stage 0. The difference between stage 0 and 3 is like the difference between a regular fiesta and the ST. Sound: I was a bit concerned beforehand because I really didn't want a ridiculously loud little hatchback, but I was very happy with this. You get a great exhaust note when you lay into it, but its very tame under normal driving conditions. The videos of the exhaust here and on you tube are pretty close to the real sound, but don't quite reproduce the level bass you get in real life. The exhaust noise doesn't really come alive until around 3000 RPM. It starts out deep and rises nicely in pitch as you go through the RPM band. It also gives a nice, but not too loud, crackling / popping noise when you lift of the gas and/or downshift. When cruising on the highway, you will barely notice any exhaust noise until you get up around 75 mph. Around 80 it does start to get pretty load and drones a little bit, but if you turn the stereo up just a little bit you will barely notice. I usually stay at 75 or less so its not been a problem at all for me. There is a brief moment of resonance somewhere around 3000-3200 RPM. When accelerating from a stop you go past it so quick you never notice it at all. I only notice when accelerating slowly between 75 & 80 on the highway. Even then its not a big deal. Build Quality: Like everything else I've bought from Cobb, the quality is fantastic. The walls of the exhaust pipe are considerably thicker than the stock and the quality of the welds are much better. Install: I have to say this is the 1st Cobb install guide that is 100% accurate. There were some areas where the exhaust was very close to the heat shielding so I pushed the heat shielding back some to make sure it wouldn't rub against the exhaust. As far as difficulty goes, I've done the entire stage 3 install myself and maybe with exception of the rear motor mount, this was the easiest install I've done. Customer Service: It shipped within 24 hours and arrived in Chicago 3 days later. This is actually first time that a part shipped in 24 hours. While everything on Cobb's site seems to say ships within 24 hours, almost every other part I've ordered took 7-10 days to ship.

Rated 5 out of 5 by from Amazing sound Got this with a tune, the power is very nice at a full stage 3. It rattles with the OEM hangers, the Cobb ones are a must. Cobb only gives 3 in their set, there are four. Cobb says to replace the rear 3. Once I installed those no rattles. (I also had a rattle before the TBE install when idlingly with the AC on, the hangers got rid of that too). A stock FiST makes about 180 on the dyno I was tuned on, mine was 206whp/285 ftlbs at the wheel.

Rated 5 out of 5 by from Beaufiful looking, great sounding Love this exhaust so far. Quality is excellent with beautiful welds and finish. The two Cobb logos look awesome on the tips peeking out under the diffuser. Sounds great and gets pretty loud when you put your foot in it but quiets down nicely when cruising. I love the burble when slowing down in around town driving. This exhaust has added some needed excitement and drama to my driving experience. It just gives the car a more serious sound.

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.

Rated 5 out of 5 by from Outstanding sound for a Catback I have had this on my 2016 FiST For about a month now and i absolulty love it! It looks great and sounds even better. The tips stick out a little longer than the stock and give the car a nice touch, the sound... I cant help but smile when I step on the gas. I especially love how it pops when downshifting. At idle and calm driving it sounds like stock, but when you step on it or get in the higher revs boy does it sing. I highly recommend getting the Exhaust hangers they make a difference and prevent the rattling the stock ones cause. Installation was not to hard. A lift makes it so much easier, just cut the old, replace the hangers, and piece by piece add the new. It took me no more that 2 hours from start to driving again.

Rated 5 out of 5 by from Beautifully manufactured, great sound and looks The exhaust was packaged very well, the quality of this product is exceptionally clear once out of the box. Install was easy. Gives the car just the right sound, with no drone on the highway or at high speeds. One nice aspect is when you are coming off throttle it occasionally will burble and "pop" which isn't loud but adds a nice little sound to your drive. Overall extremely happy and would highly recommend this exhaust!
