Service Completed: Custom Dual Rear Exhaust Section Upgrade

At MIJ Exhaust Ltd, we recently completed a custom rear exhaust upgrade on this BMW 650i Sport 4.8L Petrol, enhancing both the sound and rear-end appearance with a bespoke stainless steel fabrication.

For this build, we manufactured and installed a custom dual rear exhaust section, carefully designed to complement the naturally powerful character of the 4.8-litre V8 engine. The new rear section was fabricated in-house to replace the original components, improving exhaust flow characteristics while refining the overall tone of the vehicle.

The system retains a dual-exit configuration, giving the BMW a balanced and performance-focused rear-end appearance that suits the aggressive styling of the 6 Series. The upgraded rear section also provides a more purposeful and deeper exhaust note, allowing the V8 engine to deliver a richer and more engaging soundtrack throughout the rev range.

At MIJ Exhaust Ltd, we specialise in custom stainless steel exhaust fabrication for performance and luxury vehicles alike. Every system is built to suit the individual car and customer requirements, ensuring the right balance between sound, appearance, and everyday usability.

Rather than offering a one-size-fits-all solution, we tailor each build to achieve the desired result—whether that’s a subtle refinement or a more aggressive transformation.

As with all of our exhaust work, this system was fully fabricated and installed in-house by our experienced stainless steel exhaust fabricators, ensuring excellent fitment, long-term durability, and a professional finish throughout.

Be sure to watch the accompanying sound test video to hear the enhanced V8 exhaust note and see the completed dual rear exhaust upgrade in action.
