Developed for precision, engineered to last
Stone Exhaust engineers begin with 3D scanning of the OEM system to analyse pipe diameter, routing and bend angles. 3D flow simulation is used to optimise gas flow, thermal behaviour and pressure zones. The result is an OEM fitment Golf R MK7 catback exhaust with enhanced flow, tone and reliability.
Using a 7 axis CNC bending machine, Stone achieve up to 98 percent roundness and maintain only 25 percent outer bore wear at 180 degrees, preventing airflow obstruction and welding fracture issues. Combined with crisscross and overlapping welds plus direct spot welding by mechanical arms, this system delivers consistent quality and durability under high thermal stress.
