Austrian‑built valve‑controlled rear section with quad 84 mm tips for Audi S3 8V Sportback facelift

Looking for a serious sound upgrade for your 2.0 TFSI without drone or compromise. This premium stainless rear section is a valve‑actuated sports back box designed specifically for the S3 8V MQB platform. It delivers a richer, deeper tone under load, crisp cold starts and refined cabin manners when the flap is closed. Built in Austria, shot blasted for durability and engineered to reduce back pressure, it sharpens throttle response and enhances the character of your quattro hot hatch.

We run this system on our own S3 and have fitted it for many customers. Feedback is consistently positive on build quality, fit and the addictive soundtrack. If you want a high quality valved rear section that keeps OE usability and raises the excitement, this ticks every box.
