Milltek Sport Race Cat-Back Exhaust (Loudest) – 2022+ VW Golf GTI (MK8/MK8.5)

Give your 2022+ Volkswagen GTI a deeper, substantially more aggressive exhaust note with the Milltek Sport Race Cat-Back Exhaust System. Designed for MK8 and MK8.5 GTI owners who want Milltek’s loudest configuration, this system combines 80mm T304L stainless-steel pipework with a non-resonated layout and rear-silencer bypass.

Important: This is Milltek’s Race—or loudest—configuration. It is intentionally louder both inside and outside the vehicle. If you want a more restrained exhaust for frequent highway driving, consider the Milltek Road+ Cat-Back Exhaust System instead.

• Product images should be used to identify the selected tip finish; component appearance may vary slightly.

Frequently Asked Questions

Is this Milltek’s loudest exhaust for the MK8 and MK8.5 GTI?

Yes. This is Milltek’s Race configuration, which replaces the rear silencer with a bypass section for maximum exhaust volume.

What is the difference between the Race and Road+ systems?

The Race system uses a rear-silencer bypass and is the loudest option. The Road+ system incorporates a rear silencer to provide a more moderate exhaust level for customers who want additional sound without choosing the loudest configuration.

Will this exhaust fit my GTI if I do not know whether it is an MK8 or MK8.5?

For North American vehicles, the 2022–2024 GTI is the MK8 and the 2025+ GTI is the facelifted MK8.5. This listing covers both generations.

Does it fit the Volkswagen Golf R?

No. The Golf R uses a different exhaust configuration, but Milltek does offer the Race version for the Golf R and that can be found here.

Does this system require an aftermarket downpipe?

No. It can connect to the factory downpipe and factory emissions equipment.

Is an ECU tune required?

No. A tune is not required for installation of this cat-back exhaust.

Does the system remove the catalytic converter or GPF/OPF?

No. The system begins downstream of the factory emissions equipment and does not replace the catalytic converter or downpipe.

Will this exhaust drone?

This is the loudest Race configuration, so increased cabin volume and some drone should be expected. The exact experience varies by speed, transmission and other exhaust modifications. Customers particularly concerned about highway volume should choose the Milltek Road+ system.

Is this exhaust valved?

No. This is a non-valved exhaust system.

Do the different tip finishes change the sound?

No meaningful sound difference should result from the tip finish. Choose the option based on appearance and the corresponding Milltek part number.
