Moreover, Stone Exhaust has embraced advanced tech solutions in the production process. The exhaust system is constructed using a 7-axis CNC Bending Machine, renowned for its high levels of precision delivery.

The system is intricately molded with an accuracy error under 0.025mm, ensuring optimal performance while preventing airflow obstruction and welding fractures. In addition to this, the exhaust system also boasts of a Crisscross and Overlapping Welding Technique. Used for the flange between the turbo and the downpipes, this technique strengthens the connection points, enhancing endurance, and tolerance to withstand extreme temperatures.
