Audi 8V RS3 Catless Downpipe With Heat Shield

Unleash the full performance potential of your Audi RS3 8V with this Catless Downpipe featuring full heat-shielded construction, engineered to maximise exhaust flow and withstand the extreme temperatures of the legendary 2.5 TFSI engine. Designed for tuned and high-boost applications, this downpipe provides a dramatic improvement in turbo efficiency, throttle response, and exhaust sound.

Constructed from premium 304 stainless steel and wrapped in multi-layer woven thermal shielding, this downpipe keeps engine bay temperatures under control while delivering maximum flow. The catless design removes all upstream restrictions, allowing the turbo to spool faster and breathe more freely — making it an essential upgrade for Stage 2 and big-turbo RS3 builds.

Whether you're chasing faster spool, bigger power gains, or an aggressive motorsport exhaust note, this downpipe delivers serious performance with OEM-grade fitment.

Please Note

This downpipe suits DAZA engine cars only and does not fit the earlier CZGB engine. Engine code is the deciding factor rather than build year, because the changeover happened mid-production. If you are unsure which engine your car has, send us your VIN and our team will confirm it before dispatch.

This is a catless downpipe intended for off-road or motorsport use only.
Check local emissions regulations before installation.
