Upgrade Your BMW M3 or M4 with the Remus 081023 1510-5 Racing GPF-Back Exhaust System

The BMW G80 M3 and G82 M4 are already icons in the performance world, but for drivers who want a deeper, more aggressive sound and improved exhaust flow, the Remus 081023 1510-5 BMW G80 G82 Racing GPF-Back Exhaust System offers a premium solution. Designed for both standard and Competition models, this racing-focused exhaust system transforms the driving experience through enhanced acoustics, reduced back pressure, and precision engineering. Whether you’re a dedicated track enthusiast or an owner seeking a more engaging feel behind the wheel, this system delivers a noticeable upgrade in performance and character.

What Is the Remus Racing GPF-Back Exhaust System?

The Remus 081023 1510-5 Racing GPF-Back Exhaust System is a high-performance exhaust upgrade engineered specifically for the BMW G80 M3, G82 M4, and their Competition variants. Installed from the Gasoline Particulate Filter (GPF) rearward, this system replaces key factory components—including the front silencer—and introduces a racing-spec sport exhaust with integrated valves. It is constructed from 100% stainless steel with a shot-blasted finish for durability and precise fitment.

This system is designed for maximum performance and sound enhancement. It increases exhaust tube diameter from the OEM 70 mm to Remus’ 76 mm piping, improving exhaust flow and supporting more efficient engine performance. Valve control is retained using the car’s original actuators, ensuring seamless integration with factory driving modes.

Why Enthusiasts Choose the Remus 081023 1510-5 System

Remus is a respected name in the performance exhaust industry, and this system brings together several advantages that appeal to BMW M owners looking to elevate their driving experience.

Aggressive, motorsport-inspired exhaust note
Improved exhaust flow and reduced back pressure
Lightweight stainless-steel construction
Handcrafted quality made in Austria
Perfect fitment using OEM mounting points
Closed-valve and open-valve sound control using factory systems

Combined, these features deliver a more engaging and responsive driving experience while maintaining the refined feel expected of modern BMW M cars.

How the Remus Racing Exhaust Enhances Performance

This GPF-back system offers real-world performance benefits thanks to its revised piping and freer-flowing design. The increased diameter and reduced internal restrictions allow the S58 engine to exhale more efficiently, supporting improvements in throttle response and power delivery—especially noticeable during spirited driving.

Because the system retains the factory valve control, drivers can switch between quieter and more aggressive sound modes depending on their driving environment. In Sport and Sport+ settings, the system delivers a raw, motorsport-like tone that significantly enhances the emotional experience of driving an M3 or M4.

Who This Racing Exhaust System Is For

The Remus 081023 1510-5 Racing GPF-Back Exhaust System is ideal for owners who:

Want a louder, more aggressive exhaust note than stock
Track their vehicle and require a freer-flowing setup
Prefer high-quality aftermarket parts engineered for performance
Value stainless-steel construction and long-term durability
Want an exhaust that pairs well with tuning and ECU remapping

Because this is a racing exhaust without ECE approval, it is intended for track use. The installation requires cutting the original exhaust system, making professional installation highly recommended. Remus also notes that ECU remapping is beneficial for optimal performance and to prevent check engine lights when using racing components.

Tailpipe Options for Personal Customization

The system does not include tailpipes by default, allowing buyers to select from a range of premium Remus quad tailpipe designs to match their preferred look. Available styles include chromed stainless steel, carbon-fiber options, and black chrome variants. Tailpipe sizes range from 98 mm to 102 mm, giving the rear of the car a more aggressive stance while complementing the upgraded exhaust sound.

Compatibility Across G80 and G82 Models

The Remus 081023 1510-5 BMW G80 G82 Racing GPF-Back Exhaust System is compatible with:

BMW G80 M3 (2021+, with or without GPF)
BMW G80 M3 Competition (2021+, with or without GPF)
BMW G82 M4 (2021+, with or without GPF)
BMW G82 M4 Competition (2021+, with or without GPF)

Before shipping, a compatibility check is performed using your registration number or VIN to ensure the system fits your vehicle. This provides peace of mind and avoids issues during installation.
