Milltek Filter-back Exhaust for Toyota/Lexus Yaris Gen 1 - GR & GR Circuit Pack 1.6T (OPF/GPF Models Only) (2020-2024) – Sharper Sound, Filter Retained
This is Milltek's particulate filter-back system for the Toyota/Lexus Yaris Gen 1 - GR & GR Circuit Pack 1.6T (OPF/GPF Models Only). It replaces everything downstream of the factory diesel or petrol particulate filter with wider-bore pipework and re-tuned silencers, cutting back pressure and sharpening the exhaust note. The filter itself is left exactly where the manufacturer fitted it, so emissions equipment is unaffected. It's offered in non-resonated or resonated EC approved versions and 5 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's the right choice if you want a sportier sound and a genuine, if modest, flow improvement on a filter-equipped car, without going anywhere near the parts of the system that keep it emissions-compliant.

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-115 Burnt Titanium, GT-115 Cerakote Black, GT-115 Titanium, JET-115 Carbon Fibre, GT-115 Polished. The finish is cosmetic and does not change the sound.
Does it fit the Toyota/Lexus Yaris Gen 2 - GR 1.6T (OPF/GPF Models Only)?
No. For that car, choose the Milltek Filter-back Exhaust Toyota & Lexus Yaris Gen 2 GR 1.6T OPF/GPF 24+.
Is it road legal?
Some versions are EC approved; check the EC Approved line in the specification for the option you choose.
Do I need a remap?
No. It fits behind the factory particulate filter, so no software changes are needed.
Does it keep the factory particulate filter?
Yes. It fits behind the factory particulate filter, which stays in place.
How long does it take to fit?
Milltek quotes approx. 1.5 to 2 hours.
