Catless component for off-road/competition use only. CEL likely without tune.

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
• Integrated heat shield for engine-bay thermal management
• OEM flanges — direct bolt-on at turbo and cat-back
• Catless / off-road configuration
• Unlocks the distinctive 5-cylinder soundtrack the EA855 is famous for

• Material: Stainless steel
• Cat configuration: Catless (off-road / race use)
• Construction: TIG-welded, includes heat shield
• Engine: EA855 EVO2 2.5 TFSI (DAZA code)
• Configuration: Downpipe + midpipe complete assembly
• Tune: Required (APR, Unitronic, MRC, IE, Revo, etc.)

Off-road / race use only. Not intended for road use in jurisdictions with emissions compliance requirements. Buyer is responsible for ensuring legal compliance with local regulations.

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.

The AToM V2 for the Mk8 GTI is built on the same induction philosophy that earned this kit a global dealer network — a true cold-air intake that seals to the hood, isolates incoming air from engine-bay heat, and feeds the turbo through a free-flowing 100 mm hard pipe.

On the Mk8 the factory inlet is the bottleneck. Our 56 mm turbo inlet flange opens the throat, the 120 mm reverse-mounted cone pulls maximum volume through a full-width cowl, and the 160 mm accumulator / heat shield holds cold air right at the filter so the turbo always sees the densest charge available.

Dyno-validated on stock-turbo Mk8 GTI: back-to-back runs against the factory intake on a Mustang chassis dyno, with matched ambient conditions and consistent fluid temps. No cherry-picked runs — average of four pulls per setup.

• 100 mm (4″) case outlet for unrestricted turbo feed
• 4-ply steel-reinforced turbo inlet pipe — 100 mm inlet ID, 76 mm outlet ID
• 56 mm ID turbo inlet flange with Viton O-ring (heat-resistant seal)
• 160 mm air accumulator + heat shield isolates filter from engine-bay heat
• Reverse-mounted 120 mm washable cone filter
• Full-width air cowl ducts cold air from the front of the engine bay
• Rubber hood seal for a tight underside fit
• Direct OEM mounting points — no permanent modification

• Platform: MQBe (Modular Transverse Matrix — second generation)
• Engine: 2.0 TSI EA888 evo4 (Gen 4)
• Vehicle: VW Golf GTI Mk8 (2022–2024) and Mk8.5 facelift (2025+)
• Case outlet: 100 mm (4″)
• Filter: 120 mm reverse-mount cone, washable
• Tune required: Recommended — submit datalog for boost-strategy review

Fitment note: Due to the large ducting that scoops maximum air, certain aftermarket hoods with centre vents may have clearance issues. Check your hood profile before ordering if you run an aftermarket bonnet.

Do I need a tune?
A tune is recommended. The intake will install and run on a stock ECU, but to get the full power gain and protect boost-strategy headroom, submit a datalog to your calibrator after install so they can review and adjust if needed.

Will it fit with my aftermarket hood?
The full-width cowl and 160 mm accumulator sit high in the engine bay. If your hood has a centre vent or a recessed underside, check clearance before ordering. Stock hoods fit without issue.

Is the filter washable?
Yes. The 120 mm cone filter is fully serviceable — clean with intake cleaner and re-oil per the manufacturer’s instructions. Replacement filters are available as a separate SKU.

How does this compare to the Mk7 RACE V2?
Same induction philosophy — 100 mm case outlet, 120 mm filter, sealed cold-air feed — rebuilt for the MQBe engine bay and the Mk8 GTI’s turbo position. The Mk8 needs the new 56 mm flange and a re-shaped accumulator to clear the EA888 evo4 packaging.

What’s in the box?
Turbo inlet flange (56 mm), 4-ply turbo inlet pipe (100 mm → 76 mm), 160 mm air accumulator / heat shield, full-width cowl rubber hood seal, all mounting hardware.
