Volkswagen MK8 Golf R Stainless Steel Valved Catback Exhaust

Volkswagen MK8 Golf R Stainless Steel Valved Catback Exhaust

Transform the sound and character of your MK8 Golf R with this Stainless Steel Valved Catback Exhaust System — engineered to deliver an aggressive exhaust note, improved exhaust flow, and the versatility of switchable valves for both everyday driving and spirited performance.

Designed specifically for the MK8 Golf R and its EA888 Evo4 platform, this system replaces the restrictive factory rear section with a high-flow mandrel-bent stainless steel design. At the press of a button you can move between a refined, comfortable tone and a deep, aggressive motorsport-inspired soundtrack.

Manufactured from premium T304 stainless steel with precision TIG welding throughout, it offers exceptional durability, corrosion resistance and long-term reliability. Whether paired with the factory downpipe or an upgraded catted or catless unit, it delivers sharper throttle response, enhanced turbo acoustics and a significantly more engaging drive.

The stainless option for owners who want the full valved experience without stepping up to titanium.
