Engineering that delivers
Stone Exhaust engineers 3D scan the OEM MK7.5 Golf GTI exhaust to analyse pipe diameter, routing and bend angles. Using simulation to map gas flow, thermal zones and pressure, the design is refined for performance and reliability. The 7-axis CNC bending machine achieves approximately 98 percent roundness with minimal outer bore wear at tight bends, helping prevent flow disturbance and maintaining strength. Combined with direct spot welding, crisscross and overlapping weld techniques, this Golf GTI cat-back exhaust is built to perform and last.
