Before you can continue, you must agree to all of the following terms:
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal-to-metal contact. In order to keep the two components from touching each other and generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurized after carrying out this procedure. Please contact us on info@mlperformance.co.uk for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.
We are proud to introduce you to the state of the art Stone Exhaust OEM Integrated Valve Catback Exhaust System, to enhance the performance and sound of your BMW F20 3 Doors 120i,Ā F21 3 Doors 120i,Ā F22 Coupe 220i & F23 Convertible 220i with the B48 engine.
Stone Exhaust has been developing world's best exhaust system since 1998, starting with 3D scanning and reverse engineeringĀ the OEM system, this allowsĀ the Stone engineers toĀ design a 100% OEM fitment exhaust with precision. With our in-house dyno, your BMW exhaust system is proven to produce more power with the enhanced Stone signature exhaust sound.
The OEM Integred Valves(s) option allows your exhuast system to operate as standard, where the onboard computer (ECU) will control the opening and closing of the valves automatically.

R&D and 3D Scanning
Stone Exhaust engineers use reverse engineering by 3D scanning OEM parts to understand their functionality and identify weaknesses. Data has been collected continuously in order to analyze factors such as pipe diameter, route and degrees of the bending angles of the B48 Exhaust Systems.
During R&D, Stone Exhaust utilizes the 3D simulation software to stimulate the exhaust gas flow movement, thermal and pressure rise zone. Progressive improvements were continually made until the optimal performance was achieved.
7 Axis CNC Bending Machine
Stone Exhaust SystemĀ are constructed utilizingĀ a 7 axis CNC Bending Machine which is the ultimate machine for high levels of precision delivery, necessary for industries such as the aerospace and defense industries.
With the state-of-the-art bending machine, Stone Exhaust has achieved the industryās standard to an impressive 98% roundness, whilst maintaining the wear of the outer bore at only 25% at 180Ā°. Airflow obstruction and welding fracture problems are prevented by utilizing this technology. With the combination of the CNC Bending machine, Reverse Engineering and 3D Design Scanning, Stone exhaust has created an integrally molded exhaust pipe with an accuracy error under 0.025mm.
Ā
Crisscross and Overlapping Welding Technique
The flange between the turbo and the downpipes reaches extreme temperatures (800ā to 1100ā) which creates stress on the connection point. By utilizing both welding techniques to increases the width and penetration of welds. This increases the endurance and tolerance of these connection points, leading to quality products with reliable performance.
Ā
Direct Spot Welding
Our highly skilled engineers perform direct spot welding to increase product strength. This is undertaken by mechanical welding arms, proven to achieve greater precision and penetration in their welds compared to manual welding, resulting in an end product that is a work of art.
