Milltek Cat Back Exhaust Honda Civic Type R FL5 2.0 i-VTEC OPF/GPF or Non-OPF/GPF 22+

Milltek Cat-back Exhaust for Honda/Acura Civic Type R FL5 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models) (2022 onwards) – Sharper Sound, Reduced Back Pressure

This is Milltek's cat-back system for the Honda/Acura Civic Type R FL5 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models). 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, road+ part resonated or resonated EC approved versions, valved or non-valved versions and 8 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.

Should I choose the valved or non-valved version?

The valved version lets you switch between a quieter tone and the full exhaust note. Choose non-valved if you want the same sound all the time.

Which tailpipe finishes are available?

You can choose from: GT-115 Brushed Titanium, GT-115 Burnt Titanium, GT-115 Cerakote Black, GT-115 Polished, JET-115 Carbon Fibre, GT-100 Brushed Titanium, GT-100 Burnt Titanium, JET-102 Carbon Fibre. The finish is cosmetic and does not change the sound.

Does it fit the Honda/Acura Civic Type R FK8 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models)?

No. For that car, choose the Milltek Cat-back Exhaust Honda Civic Type R FK8 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models) 17-22.

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 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.

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.
