R&D, flow and build quality
Stone Exhaust engineers 3D scan the OEM MINI exhaust to analyse pipe diameter, routing and bend angles, then simulate gas flow, thermal zones and pressure rise to optimise performance. The 7 axis CNC bending process delivers up to 98 percent roundness and minimal outer bore wear at tight 180 degree bends, helping to prevent flow restriction. Precision mechanical welding, crisscross and overlapping welding, plus direct spot welding increase strength and durability for long-term reliability.
Warranty
