The Blaze RS3 / TTRS downpipe + midpipe assembly replaces the restrictive factory exhaust front section on every DAZA-coded RS3 8V.1 and TTRS 8S. The factory unit’s pre-cat and primary cat severely choke the 5-cylinder’s distinctive sound and exhaust flow.

Two-piece downpipe + midpipe construction in stainless steel with integrated heat shield. OEM flange geometry at the turbo end and the cat-back end — direct bolt-on with no fabrication.

Tune required. Without a tune the car will throw a check engine light. Any major Audi 2.5 TFSI tuner (APR, Unitronic, MRC Tuning, IE, Revo) clears the code and unlocks full benefit.

• Downpipe + midpipe complete assembly (two pieces)
• Stainless steel construction with TIG welds

How do I know if I have the DAZA engine?
DAZA is the engine code for the 2017–2020 RS3 8V.1 (pre-facelift) and 2017+ TTRS 8S. The engine code is stamped on the cam cover and listed in your VIN decode under engine designation. If you have a 2020.5+ RS3 with the 8V.2 facelift body, you likely have the newer DNWA engine and this part won’t fit.

Does it fit my RS3 8Y or facelift 8V.2?
No — both use the newer DNWA engine which has different exhaust routing.

Do I need a tune?
Yes — without a tune, the missing cats trigger a CEL. Any major Audi 2.5 TFSI tuner (APR, Unitronic, MRC Tuning, IE, Revo) clears it.

What’s in the box?
The downpipe, the midpipe, integrated heat shield, OEM-spec gaskets, and mounting hardware.

Is this legal on public roads?
This is a catless off-road / race exhaust. Road-legality depends on your country and local emissions requirements. Buyer is responsible for confirming legal use in their jurisdiction.
