Direct bolt-on downpipe for the BMW N55 single-turbo straight-six. Improves exhaust flow, reduces back pressure, delivers a deeper exhaust note.

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

Mid-section X-pipe assembly with included heat shield plate. Pairs with catless DPs or OEM DPs.

What is an S58 2-in-1 midpipe?
A 2-in-1 midpipe merges the twin-exit S58 downpipe outputs into a single large-bore tube before the rear silencer, delivering a more unified exhaust tone and improved flow versus separate parallel tubes – popular for track-focused G80/G82/G83 builds.

Which models does the S58 2-in-1 midpipe fit?
The S58 2-in-1 midpipe fits the BMW G80 M3, G82 M4 Coupe, G83 M4 Convertible, and G87 M2 Competition (S58). Please verify your chassis before ordering.

Will this increase cabin drone?
Catless 2-in-1 midpipes produce a more aggressive exhaust character. At motorway speeds, some additional resonance is present but is generally manageable, especially with a quality rear silencer.

Can I use this with the OEM rear silencer?
Yes, the Blaze S58 2-in-1 midpipe connects to the OEM rear silencer and is fully compatible with the factory rear exhaust.

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 Blaze Golf R / S3 8V downpipe replaces the restrictive factory downpipe + catalytic converter on every MQB EA888 Gen 3 platform car running the IS38 turbo. Free-flowing stainless construction with a bolt-on heat shield for engine-bay management.

Direct OEM fit to factory turbo and factory midpipe — no fabrication required. Includes integrated heat shield to protect surrounding components from the higher exhaust temperatures of a catless setup.

Tune required. The car will run on stock ECU but will throw a check engine light without a tune. Any major MQB tuner (APR, Unitronic, Revo, Cobb, etc.) clears the code and unlocks the full benefit.

• Stainless steel construction with TIG welds throughout
• Integrated heat shield for engine-bay thermal management
• OEM turbo flange — direct bolt-on to factory IS38 turbo
• OEM midpipe flange — bolts to factory exhaust, no other mods required
• Catless / off-road configuration
• Compatible with stock IS38 and most hybrid IS38 turbo upgrades (Vortex XL, TTE, Littco, CTS, LM series)

• Material: Stainless steel
• Cat configuration: Catless (off-road / race use)
• Construction: TIG-welded, includes heat shield
• Engine: MQB EA888 Gen 3 2.0 TSI
• Turbo compatibility: IS38 (factory + most hybrid upgrades)
• Tune: Required (APR, Unitronic, Revo, Cobb, 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.

Does it fit my Audi S3 8V?
Yes. The S3 8V shares the same MQB platform, EA888 Gen 3 engine, and IS38 turbo as the Golf R Mk7/7.5. Direct bolt-on.

Will it fit my Mk8 Golf R or 8Y Audi S3?
No. Those cars use the EA888 evo4 with different turbo packaging. See our dedicated Mk8 R / 8Y S3 range.

Do I need a tune?
Yes — without a tune, the missing upstream cat triggers a CEL. Any major MQB tuner (APR, Unitronic, Revo, Cobb) clears it.

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

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