Milltek Secondary Cat-back Exhaust for Subaru BRZ 2.0-litre (2012-2021) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Subaru BRZ 2.0-litre. 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 or resonated EC approved versions and 4 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-115 Polished, GT-115 Titanium, GT-115 Brushed Titanium, GT-115 Cerakote Black. The finish is cosmetic and does not change the sound.
Will it fit the Subaru BRZ 2.4 Litre?
Yes. Milltek lists this part for the Subaru BRZ 2.4 Litre as well as the other models in the fitment list above.
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.
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.
