Valved Exhaust with Middle Silencer Delete and 200 Cell OPF/GPF Replacement

The Capristo Valved Exhaust for the BMW M3 (G80 Sedan and G81 Touring) is a comprehensive performance solution designed to liberate the S58 engine from the heavy sound restrictions of the factory setup. This "Race" configuration combines German precision engineering with a high-flow architecture to deliver a visceral, high-frequency soundtrack.

Crafted from high-grade T309 (1.4828) Stainless Steel, this system possesses sonic resonance properties similar to Inconel. It is hand-polished to a mirror finish and utilizes 3D laser-scanning to ensure a 100% perfect bolt-on fitment to the original BMW mounting points.

Performance & Stance

• Massive Acoustic Jump: By removing the primary bottlenecks, the sound level increases from the factory 102dB to a staggering 126.7dB with the valves open. This transforms the M3's muted tone into a sharp, aggressive roar.

• Middle Silencer Delete: This section replaces the bulky factory mid-box with "spare" straight pipes, eliminating exhaust turbulence and shedding significant weight from the centre of the car.

• 200-Cell OPF/GPF Replacement: This high-flow solution replaces the highly restrictive factory Otto Particulate Filters. It allows the turbos to spool faster, reducing backpressure and unlocking measurable gains in horsepower and mid-range torque.

• Sharpened Response: The combination of the mid-delete and 200-cell cats results in a much more immediate throttle response and a distinct "crack" during gear shifts in Sport+ mode.

Engineering & Customization

• OEM Valve Integration: The system is designed to work seamlessly with the original BMW electronic actuators. This allows you to retain full control of the exhaust flaps through the factory M-Drive settings—allowing for a "subdued" city drive or an unrestricted "open" symphony.

• Wicrom Exhaust Tips: The system is finished with Capristo's iconic Wicrom tips, featuring a high-lustre outer shell and anodised aluminium inner inserts. These are available in Black, Red, or Silver, allowing you to match the accent colours of your M3’s interior or brake callipers.

• Heat Management: T309 steel is specifically chosen for its ability to handle extreme temperatures (exceeding 600°C), ensuring the system remains structurally sound even under intense track-day thermal loads.

Installation Notes

• G80 & G81 Compatibility: Specifically engineered for the S58-powered M3 Sedan and M3 Touring (including Competition models).

• No Cutting Required: This system is a direct replacement, ensuring the modification is reversible and preserves the integrity of the vehicle's chassis.
