It has been quite a while since our last update, and we are glad to be wrapping up this project! One of the reasons for this delay is that, based on your feedback, we have decided to add a few more options for this exhaust system.
You might remember from a previous post, that our engineers enjoyed the louder sound of our non-resonated exhaust after having listened to both the resonated and non-resonated versions. Since there were no improvements in horsepower with either option, we based our decision to create the exhaust on sound only.
To refresh your memory, here are some photos of the resonated and non-resonated sections of the exhaust. Aside from this small difference, the rest of the exhaust layout is the same.

It's been a while since our last update on the Fiesta ST cat-back exhaust and we are excited to let you in on the details of the final prototype! The last detail to square away was the exhaust tips. While the tips we had were decent, we found them a little on the plain side so we switched it up. Rather than the single-wall tips, we went with a dual-walled setup that we think look much better on the ST and will hold up better over time. Check out some photos below!

In our last post we took a good look at the stock Fiesta ST exhaust and the initial design of our cat-back exhaust. The exhaust was fabricated and installed on the car and then it was time to test the stock system.
To Resonate or Not to Resonate
Getting the sound just right was quite a process. Our initial prototype featured 2.5" piping with a single rear muffler. This design did not feature a resonated mid-pipe unlike the stock unit. The initial design was sound tested on the dyno and also test driven by several members of the team. While we loved the low growl of the exhaust as it was, we wanted to test a resonated version before settling on a final design. As with all exhaust development projects, we are aiming for a final product that sounds great on throttle while still being
As many of you are aware, here at Mishimoto we have been going Fiesta crazy developing various Fiesta ST parts such as;
- Performance Aluminum Radiator
- Oil Cooler Kit
- Performance Air Intake
- Direct-Fit Baffled Oil catch can
- Downpipe and Intercooler/Piping coming soon!
Up next is something that the team here has been very eager to start development on, the Fiesta ST Cat-Back Exhaust! We are excited to let you in on the details of the development of our first prototype. As with any exhaust project, we are shooting for improvement in flow over stock as well as a great overall tone that is drone-free. Check out the details and let us know how we did!
Stock Component
To begin, we gave the Fiesta ST's stock exhaust setup an once-over to see what we were working with. While it is not terrible, we do see some room for improvements. As you may have noticed, the stock exhaust has two mufflers. One rather
