Milltek Cat-back Exhaust for Volkswagen Golf MK7.5 GTi (Non Performance Pack Models & Non-GPF Equipped Models Only) (2017-2018) – Sharper Sound, Reduced Back Pressure
This is Milltek's cat-back system for the Volkswagen Golf MK7.5 GTi (Performance Pack Models & Non OPF/GPF Equipped Models Only). 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, resonated EC approved or road+ part resonated versions and 5 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
We recommend professional fitting on a ramp. Once fitted, check the tailpipe alignment and re-check all clamps after the first few hundred miles.
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-100 Burnt Titanium, GT-100 Cerakote Black, GT-100 Polished, GT-100 Titanium, JET-100 Carbon Fibre. The finish is cosmetic and does not change the sound.
Will it fit the Volkswagen Golf MK7.5 GTi (Performance Pack Models & Non OPF/GPF Equipped Models Only)?
Yes. Milltek lists this part for the Volkswagen Golf MK7.5 GTi (Performance Pack Models & Non OPF/GPF Equipped Models Only) 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.
