- Real time O2 sensor design helps prevent delayed readings and error codes for a clean dash and smooth drivability.
- High efficiency noble metal catalyst for effective emission control with high flow performance.
- Direct bolt on fitment using OEM mounting points - 3D scanned and CAD optimised to match the original pipe with no cutting or modification.
- SUS304 stainless steel construction for durability and corrosion resistance.
- Dual cross welding and direct spot welding for strength at high temperature turbo flange areas.
- Manufactured on a 7 axis CNC bending machine for superb roundness and flow consistency.
- UK MOT friendly and Euro 6 compliant design.
Real world performance
Compared to typical straight downpipes and conventional catted designs, Stone’s patented eddy catalytic technology has been shown to effectively increase horsepower and torque, with quicker turbo spool and a sharper throttle feel. In our experience fitting these at Nforcd, the fitment is spot on, the sound is refined yet purposeful, and feedback from customers has been consistently excellent.
Engineering that makes the difference
- Reverse engineered by 3D scanning OEM components to analyse pipe diameter, routing and bend angles for the N26 exhaust system.
- CFD simulation used to model exhaust gas flow, heat zones and pressure for optimal real world results.
- Precision manufacturing achieves exceptional roundness and weld integrity to minimise turbulence and maximise reliability.
