Austrian‑made valved back box upgrade for Audi S3 8V/8VA Sportback 2.0 TFSI quattro DJHA 228 kW (2016 onwards) — EC type approved, non‑GPF

Bring out the character of your S3 with a premium tail section that keeps factory flap control and delivers an addictive soundtrack on demand. This high quality twin rear box assembly features OE‑actuated valves, so you enjoy a refined, civil tone in Comfort and a sharper, sportier note when you want it. The finish is as impressive as the sound, with four 90 mm polished rolled‑edge outlets that fill the diffuser perfectly for a purposeful, OEM+ look.

Crafted in Austria from full stainless steel with a shot‑blasted texture, this performance rear section is engineered for reduced back pressure, lighter weight and precise fitment. EC type approval means it is road legal in Europe, making it a smart, hassle‑free sound and style upgrade for non‑OPF cars.
