Thermal R&D 3" cat back exhaust 2014-2019 Fiesta ST

$ 875.00
<
3” T304 Stainless Steel Catback System
  • Mounts to OEM catalytic converter.
  • Utilized OEM Hangers, Tip Fits OEM Valance
  • Brush finish tubing, polished tip and resonators
  • Dual 2.5” Angle cut tips

When the Ford Fiesta was finally introduced to the North American market, the engineers at Thermal were eager to get their hands on the car and see what we could do with the sound and performance. 

We started with the catback system, keeping in mind the downpipe for the full turbo-back systems would be necessary. A 3” system made was the ultimate choice, and the dual polished 2.5” stainless tips gave the system a more finished aftermarket look.

To address the drone issues that can arise from the larger 3” tubing we added a straight through resonator on the mid-pipe and a resonator on the rear section. This allows for no restriction when accelerating, but deflects the unpleasant tones that can creep in while cruising.

Overall, the Fiesta ST Catback exhaust is a system that we are very excited about launching alongside our popular Focus ST system and soon to come Focus RS system.

Best exhaust you can get

If you want something that’s matured but sounds amazing and doesn’t rattle your brain loose from drone this is your exhaust. Even with a Downpipe

Perfect sound

This exhaust is very well-engineered for both sound and fitment. Was a breeze to install and sounds miles better than my former MBRP exhaust. Absolutely no drone at the usual 3k to 3,600 rpm marks. Very happy with my purchase.

Amazing Costomer Service!

I've had this exhuast for about a week now, and I absolutely love it. It has all the things I would want for an exhuast. It has nice a nice deep tone at low rpms, but when you floor it, its like a sport bike and with the interment pops and burbles it just bring a smile on my face. Unfortunately the installer that I had chose didn't do the best job with installing the tips and they fell off, but thanks to their Costomer Service they got back to me the same day and are already looking to getting me a replacement. Absolutely amazing.

Love it!

Love the look and sound of this exhaust! Just like everyone else says, it's loud when want it to be and quiet if you need it to be. And no highway/ high speed drone!

Exactly what I wanted...

....this stock exhaust replacementis also exactly what this little car needed. Love the sound across the entire RPM range. Wanted to share something else. Had the kit installed by a local garage. When I picked the car up the old guy who installed it asked me right away where I got it. He went on to say he figured he'd have to weld it since sooo many supposed bolt on kits...in his experience....anything but bolt on. While it wasn't a supremely easy install, he was blown away by how cleanly it fit.....and the obvious quality of the components (material, bends, etc) were among the best he's ever seen on over 50 yrs of automotive repairs/upgrades. Never heard anyone in his position make comments like that. Obviously I'm very happy with the purchase.
