Milltek Cat-back Exhaust for Ford Fiesta Mk7/Mk7.5 1.0T EcoBoost (100/125/140PS) (2013-2017) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Ford Fiesta Mk7/Mk7.5 1.0T EcoBoost (100/125/140PS). It replaces everything from the factory catalytic converter rearward with wider-bore pipework, a re-profiled mid-pipe and silencers tuned specifically for this platform, cutting back pressure and sharpening the exhaust note. The factory catalytic converter stays in place, so the car's emissions hardware is left as standard. It's offered in non-resonated, resonated or road+ part resonated versions and 5 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's aimed at owners who want a noticeably different sound and a genuine, if modest, flow improvement without touching anything upstream of the cat: a straightforward bolt-on that doesn't need a remap or any other supporting mods to enjoy.

What's the difference between the resonated and non-resonated versions?
The resonated version adds extra silencing for a quieter, more refined tone. The non-resonated version leaves it out, so it is louder and more aggressive.
Which tailpipe finishes are available?
You can choose from: GT-80 Burnt Titanium, JET-80 Carbon Fibre, GT-80 Cerakote Black, GT-80 Polished, GT-80 Titanium. The finish is cosmetic and does not change the sound.
Does it fit the Ford Fiesta Mk7/Mk7.5 ST 1.6 litre EcoBoost 182PS & ST200?
No. For that car, choose the Milltek Cat-back Exhaust Ford Fiesta Mk7 & Mk7.5 ST 1.6 litre EcoBoost 182PS & ST200 13-17.
Is it road legal?
Milltek does not list EC approval for this part. Any exhaust used on the road must still meet noise and emissions rules, so check the requirements where you live.
Do I need a remap?
No. It fits behind the factory catalytic converter, so no software changes are needed.
Does it keep the factory catalytic converter?
Yes. It fits behind the factory catalytic converter, which stays in place.
What is it made from?
T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
Is there a warranty?
Yes. Milltek products are covered against defects in materials and workmanship. Contact us with your order number if you have a problem.
