Milltek Filter Back Exhaust Volkswagen Golf Mk8.5 GTi Clubsport OPF/GPF 24+

Milltek Filter-back Exhaust for Volkswagen Golf Mk8 GTi (245ps Non-GPF/North American Models Only) (2021-2024) – Sharper Sound, Filter Retained

This is Milltek's particulate filter-back system for the Volkswagen Golf Mk8.5 GTi Clubsport (300ps OPF/GPF Equipped 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 resonated EC approved or race non-resonated versions and 8 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. Race versions are the loudest and are intended for track use.

Which tailpipe finishes are available?

You can choose from: GT-115 Burnt Titanium, JET-115 Carbon Fibre, GT-115 Cerakote Black, Cerakote Black Oval, Polished Oval, GT-115 Polished, GT-115 Titanium, GT-115 Brushed Titanium. The finish is cosmetic and does not change the sound.

Will it fit the Volkswagen Golf Mk8 GTi (245ps OPF/GPF Equipped Models Only)?

Yes. Milltek lists this part for the Volkswagen Golf Mk8 GTi (245ps OPF/GPF Equipped Models Only) as well as the other models in the fitment list above.

Does it fit the Volkswagen Golf Mk8 R 2.0 TSI 320PS (GPF Equipped Models Only)?

No. For that car, choose the Milltek Filter-back Exhaust Volkswagen Golf Mk8 R 2.0 TSI GPF 21-24.

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?

It depends on the version. Milltek's fitting time for each option is shown in its specification table.

What is it made from?

T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
