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.

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.

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.

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.
