Enhance the sound and driving experience of your BMW F90 M5 or M5 Competition with the Milltek Sport 80mm Valved OPF/GPF-Back Exhaust System. Engineered specifically for BMW's 4.4L twin-turbocharged V8, this premium performance exhaust delivers a sportier exhaust note, improved exhaust flow, and refined sound characteristics while retaining the vehicle's factory emissions components.
Manufactured from premium T304L stainless steel, the Milltek Sport exhaust features mandrel-bent 80mm (3.15-inch) tubing designed to optimize exhaust gas flow and reduce restriction. The system incorporates precision-engineered connecting pipes, a rear silencer, and valved exhaust outlets for a performance-oriented sound profile.
The valved exhaust configuration provides a balance between aggressive V8 sound and comfortable everyday driving. Milltek's acoustic engineering is designed to minimize unwanted cabin resonance while producing a deeper, more engaging exhaust note during acceleration.
Unlike full exhaust systems that replace catalytic converters or particulate filters, this OPF/GPF-back configuration retains the factory emissions equipment. It is designed to integrate with the original exhaust layout while providing a significant upgrade in construction, sound, and appearance.
The exhaust is available with Polished, Cerakote Black, Brushed Titanium, Burnt/Blue Titanium or Carbon GT100 exhaust tips, allowing owners to customize the rear appearance of their M5. The 100mm round tips complement the factory rear bumper and provide a premium finishing detail.
Manufactured in the United Kingdom, the Milltek Sport exhaust is engineered for precise vehicle-specific fitment. Installation utilizes the factory exhaust hangers, although cutting of the original exhaust system is required to install the replacement rear section.
For BMW M5 owners seeking enhanced V8 sound, premium stainless-steel construction, and a refined valved exhaust system, the Milltek Sport 80mm OPF/GPF-Back Exhaust offers an excellent combination of performance and everyday usability.
