Transform the exhaust character and performance of your G87 M2 with the Blaze Performance S58 catless midpipe. Designed specifically for the 2023+ BMW M2 G87, this midpipe deletes the restrictive mid-section catalytic converter — delivering a significant improvement in exhaust gas evacuation, quicker turbo response and a dramatically more engaging sound profile.

• High-grade stainless steel construction with precision TIG welds
• Catless design removes mid-section restriction completely
• V-band connections for secure fitment and easy removal
• Direct bolt-on replacement — no modification required
• Pairs perfectly with catless or OEM downpipes

Designed for off-road / track use. ECU remap recommended to take full advantage.

What is the difference between a midpipe and a downpipe?
The downpipe connects the turbocharger directly to the exhaust system and typically houses the catalytic converters. The midpipe sits further back in the exhaust, connecting the downpipe section to the rear silencer. On the S58-powered G87 M2, the factory midpipe contains a resonator that restricts flow and limits sound – our catless midpipe removes this restriction for a more aggressive tone and improved flow.

Is this midpipe compatible with the G87 M2 Coupe and Competition?
Yes, the Blaze S58 catless midpipe is compatible with all variants of the BMW G87 M2 (2023 onwards), including the base M2 and the M2 Competition. Please confirm your specific model year before ordering as EU and ROW specifications can differ.

Will this midpipe work with the factory valved exhaust?
The midpipe replaces the factory resonator section and is compatible with the OEM valved rear silencer. However, customers on catless setups often pair the midpipe with an aftermarket rear section for full exhaust system optimisation.

What sound level increase should I expect?
A catless midpipe on the S58 G87 M2 produces a notable increase in exhaust note under hard acceleration, with a rawer, more mechanical character compared to the OEM setup. At highway cruising speeds, drone is typically minimal. Sound levels vary depending on the rest of the exhaust configuration.

Unlock the full potential of your S58-powered BMW with the Blaze Performance catless downpipe set for the G80 M3, G82 M4 and G83 M4. Replacing the restrictive factory catalytic converters, these high-flow downpipes dramatically reduce exhaust backpressure — delivering faster turbo spool, increased horsepower and torque, and a far more aggressive exhaust note.

• High-grade stainless steel construction with precision TIG welds
• Catless design for maximum exhaust flow
• Integrated heat shielding to manage underbonnet temperatures
• Direct bolt-on fitment — no cutting or custom fabrication required
• Heavy-duty V-band clamp hardware included
• Suitable for high-output tuned builds

Designed for off-road / track use. Tuning recommended to maximise power gains.

Which BMW models are the S58 catless downpipes compatible with?
These catless downpipes fit the BMW G80 M3 (2021+), G82 M4 (2021+), G83 M4 Convertible, and G87 M2 (2023+) – all equipped with the S58 twin-turbo 3.0-litre inline-six engine.

Are these downpipes street legal?
These are catless (decat) downpipes designed for track and motorsport use. They remove the catalytic converters, which makes them non-compliant with road emission regulations in most jurisdictions. They are not for road use where emissions testing is required.

Will I need a remap after fitting these downpipes?
Yes, a supporting ECU remap is strongly recommended after fitting catless downpipes. The removal of back-pressure from the catalytic converters changes the exhaust gas dynamics, and a tune will ensure the S58 delivers maximum power and prevents lean-running fault codes.

How much power can I expect to gain?
On a supporting tune, catless S58 downpipes typically contribute 15–25 bhp to an overall Stage 2 package. Combined with supporting bolt-ons and a full remap, G80 M3 and G82 M4 customers regularly achieve 550–600+ bhp on pump fuel.

Bar and plate intercooler core with larger frontal area and improved flow. Direct OEM-location bolt-on, uses stock piping.

Bar and plate intercooler with cast end tanks. 80% larger frontal area, 55% more volume than stock. No cutting required.

The G80 M3, G82 M4 and G87 M2 leave the oil cooler completely exposed to road debris and rash, which can cause catastrophic engine failure if punctured. This skid plate provides a robust shield.

Which BMW G8X models does the oil cooler skid plate fit?
Designed for the BMW G80 M3, G82 M4, G83 M4 Convertible, and G87 M2 (2023+). Protects the front-mounted oil cooler which sits low in the chassis and is vulnerable to road debris and track kerbing.

What material is the skid plate made from?
High-strength steel plate with powder coat finish, engineered to deflect road debris, stone strikes, and kerbing impacts that would otherwise damage the OEM oil cooler core.

Is the skid plate a direct fit?
Yes, uses the OEM bolt points and brackets for a factory-style fitment. No drilling or modification required. Installation takes approximately 30 minutes with a standard socket set.

Is this recommended for track use?
Highly recommended for any G80 M3, G82 M4, or G87 M2 used on circuit. Kerbing contact is a primary cause of oil cooler damage on the G8X platform.

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.

Direct replacement charge pipe for the F-Series B58 platform. Eliminates OEM weak point, supports higher boost levels.

High-flow intake manifold with integrated water-to-air charge cooler for the BMW S58 twin-turbo platform.

Which S58 BMW models does this cast manifold fit?
The S58 cast intake manifold fits the BMW G80 M3, G82 M4, G83 M4 Convertible, and G87 M2 (2023+). Not compatible with the S55 engine in F80/F82/F87 M2 Competition.

When does the S58 cast manifold become necessary?
Recommended for S58 builds targeting 650+ bhp where the OEM manifold becomes a restriction. For Stage 2 builds (500–600 bhp), the OEM manifold is typically adequate.

Is a custom remap required?
Yes. A full custom ECU remap is mandatory after manifold installation. Map the complete build on a rolling road for best results.

Is it compatible with OEM injectors?
The manifold accepts OEM injectors, but high-power builds will require upgraded injectors and additional fuelling solutions. Consult your tuner before ordering.

Combined intake manifold and water-to-air charge cooler upgrade for the G-Series B58 (Gen 2).

What is the difference between B58 Gen 1 and Gen 2 cast manifolds?
The Gen 2 cast manifold is for the B58TU engine in G-Series BMW (G20/G22/G29) and Toyota GR Supra A90. It has revised runner lengths matched to the B58TU cylinder head and is not interchangeable with the F-Series Gen 1 version.

Which models does the Gen 2 cast manifold fit?
The B58 Gen 2 cast manifold fits the BMW G20 M340i, G22 M440i, G29 Z4 M40i, and Toyota GR Supra A90 (B58TU engine).

At what power level does the cast manifold become necessary?
Beneficial for B58TU builds targeting 500+ bhp where the OEM manifold is the primary restriction. For Stage 1 and Stage 2 builds, the OEM manifold is typically sufficient.

Does it require upgraded fuelling?
High-power builds (600+ bhp) will likely require upgraded injectors. Consult your tuner for a complete fuelling strategy.

Combined intake manifold and water-to-air charge cooler upgrade for the F-Series B58.

What is a cast intake manifold and why upgrade?
A cast aluminium manifold replaces the OEM unit with larger runners and a bigger plenum, reducing the intake restriction that limits power on big-turbo B58 builds targeting 500+ bhp.

Which F-Series BMW models does the B58 Gen 1 cast manifold fit?
The B58 Gen 1 cast manifold fits the BMW M140i (F20/F21), M240i (F22/F23), 340i (F30/F31), 440i (F32/F33/F36), and M2 Competition (F87 B58 variant).

What power level justifies a cast manifold?
Recommended for Stage 3+ builds targeting 500+ bhp on the B58 Gen 1. Below this, the OEM manifold is generally not the primary restriction.

Does it require supporting modifications?
Yes. The cast manifold is part of a Stage 3+ package – fit it with an upgraded turbo, catless downpipes, intercooler, and a full custom ECU remap.
