BMW 2-Series G87 Downpipes – Catted & Decat Performance Exhaust Upgrades

BMW 2-Series G87 Downpipes – Unleash the True Power of the Next-Gen M2

The BMW 2-Series G87, launched in 2022, is the latest generation of the legendary BMW M2. Powered by the twin-turbocharged S58 3.0L inline-six engine, the G87 delivers outstanding performance straight from the factory, but there’s still hidden potential waiting to be unlocked. One of the most effective upgrades for your G87 is installing a performance BMW 2-Series G87 downpipe, which increases power, improves turbo spool, and transforms your exhaust note into a true motorsport symphony.

Why Upgrade to a Performance BMW 2-Series G87 Downpipe?

The OEM downpipe is designed with emissions and noise control in mind, but it restricts exhaust flow and limits performance. Upgrading to a high-flow performance downpipe offers several benefits:

• Substantial horsepower and torque gains – optimized exhaust flow allows your S58 engine to breathe better and deliver more power.
• Faster turbo spool – reduces turbo lag, improving throttle response and acceleration.
• Sportier, more aggressive exhaust tone – catted downpipes provide a deep, refined sound, while decat downpipes unleash a raw, motorsport-inspired roar.
• Lower exhaust gas temperatures – improved thermal efficiency enhances engine reliability under high-performance driving.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and high-performance hybrid turbo setups.

Types of BMW 2-Series G87 Downpipes

We offer a wide range of BMW 2-Series G87 downpipes designed to suit different driving styles and tuning levels:

Catted BMW 2-Series G87 Downpipes

Catted downpipes are equipped with a high-flow sports catalytic converter, delivering performance gains while remaining emissions-friendly. Perfect for daily-driven M2 builds in regions with strict emissions regulations.

Decat BMW 2-Series G87 Downpipes

Decat downpipes remove the catalytic converter completely, maximizing exhaust flow and extracting every bit of performance from your S58 engine. Ideal for track builds or areas without emissions testing.

Material Options: Stainless Steel & Titanium

Our BMW 2-Series G87 downpipes are manufactured using premium materials for superior performance, strength, and longevity:

• Stainless steel downpipes – durable, corrosion-resistant, and cost-effective, ideal for performance street builds.
• Titanium downpipes – ultra-lightweight, exceptional heat resistance, and a motorsport-grade premium finish.

Engine Compatibility

Our BMW 2-Series G87 downpipes are specifically designed for the high-performance S58 engine used in the G87 M2:

• BMW G87 M2 Downpipes – optimized for the twin-turbocharged S58 3.0L straight-six engine.
• Perfect fitment for stock turbo configurations and hybrid turbo performance builds.

Performance Gains with BMW 2-Series G87 Downpipes

Installing a performance BMW 2-Series G87 downpipe offers measurable improvements, especially when paired with ECU tuning:

• +35–75 HP with a downpipe upgrade alone.
• +80–130 HP when combined with Stage 2 ECU remapping.
• Significant torque gains for stronger mid-range and top-end acceleration.
• Sharper throttle response and reduced turbo lag for a more engaging drive.

Choosing the Right Diameter

The correct pipe diameter is essential for optimizing performance gains and exhaust efficiency:

• 3.0-inch downpipes – recommended for both stock turbo Stage 2 builds and hybrid turbo high-boost applications.

All our BMW 2-Series G87 downpipes are designed for direct bolt-on installation, ensuring perfect fitment without any cutting or welding required.

Build Quality & Engineering

Our performance downpipes are built to the highest standards using advanced engineering techniques:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• High-grade stainless steel or ultra-lightweight titanium construction.
• Precision TIG welding guarantees durability and leak-free performance under extreme boost conditions.
• OEM-style flanges and fittings provide seamless integration with factory and aftermarket exhaust systems.

Tuning Potential

Pairing your BMW 2-Series G87 downpipe with ECU remapping unlocks the full performance potential of your M2:

• Substantial increases in horsepower and torque.
• Optimized boost control and fuel mapping for maximum efficiency.
• Customizable exhaust tone depending on whether you choose catted or decat configurations.
• Smoother power delivery and enhanced drivability across all rev ranges.

Daily Driving vs Track Builds

For street-driven BMW G87 M2 builds, catted downpipes are ideal for maintaining emissions compliance while boosting performance. For dedicated track applications, decat downpipes deliver maximum exhaust flow, top-end power, and an uncompromising motorsport-inspired sound.

Conclusion

Upgrading your BMW 2-Series G87 M2 with a performance downpipe is one of the most effective modifications for extracting the full potential of the S58 engine. Whether you choose a catted or decat configuration, our range of BMW 2-Series G87 downpipes ensures premium materials, precision fitment, and proven performance gains.
