Milltek Cat-back Exhaust for Mercedes A-Class A45 AMG 2.0 Turbo (W176) (2012-2018) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Mercedes A-Class A45 AMG 2.0 Turbo (W176). 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 valved or non-valved versions, 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.
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?
Milltek quotes approx. 1 to 1.5 hours.
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.
