Engineering detail that makes the difference

Stone’s process starts by 3D scanning the factory system to analyse diameters, routing and bend geometry, then applying flow simulation to optimise gas velocity, thermal behaviour and pressure zones. The result is a rear system that fits like original equipment, flows better and sounds right.

With 7 axis CNC bending achieving up to 98 percent roundness and accuracy within 0.025 mm, plus crisscross and overlapping welds and robotic spot welding, this system is built to perform under heat and last.
