Description

We are proud to introduce you to the state of the art Stone Exhaust Valvetronic Cat-Back Exhaust System, to enhance the performance and sound of your Ford MK3 Focus ST with the 2.0T engine, manufactured after 2012. Stone Exhaust has been developing world's best exhaust system since 1998, starting with 3D scanning and reverse engineering the OEM system, this allows the Stone engineers to design a 100% OEM fitment exhaust with precision. With their in-house dyno, your Ford exhaust system is proven to produce more power with the enhanced Stone signature exhaust sound.

The Cat-Back Valvetronic System comes with a separate remote controller that gives you full control of the exhaust, allowing you to open and close the valves with a click of a button. You can also set it in auto mode for the valves to open at a certain rpm automatically. The Stone Valvetronic system is a plug and play system, and connects to your OBDII port, which can be installed within a few minutes.

      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 2.0T Exhaust System found on the Ford MK3 Focus ST 2.0T. 

      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.

      Valvetronic System

      The Stone Valvetronic System was independently researched and developed in house. The system forgoes the conventional design of complicated wiring and the rubber inside the valve which is prone to aging, to ensure longevity.

      With the Valvetronic remote control providing three modes to choose from: ON / OFF / AUTO, this allows for instant switching between modes in accordance to driving conditions faced. So, let the STONE Valvetronic System adapt to your vehicle’s needs.

      The Valvetronic remote control has 3 modes, ON / OFF / AUTO, which allows you to open and close the valve at a click of a button. The Auto mode allows customization of the opening and closing of the valve at a predefined RPM.

       

       

      7 Axis CNC Bending Machine

      Stone Exhaust System are constructed utilizing 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 industry’s standard to an impressive 98% roundness, whilst maintaining the wear of the outer bore at only 25% at 180°. 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.

        Crisscross and Overlapping Welding Technique

        The flange between the turbo and the downpipes reaches extreme temperatures (800℃ to 1100℃) 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.
