Milltek Cat-back Exhaust for Honda/Acura S2000 2.0 and 2.2 litre AP2 (2004-2009) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Honda/Acura S2000 2.0 and 2.2 litre AP2. 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 2 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.

Installation

Which tailpipe finishes are available?
You can choose from: Polished Oval, Cerakote Black Oval. The finish is cosmetic and does not change the sound.

No. For that car, choose the Milltek Cat-back Exhaust Honda S2000 2.0 litre AP1 99-03.
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.
