- Real-time O2 sensor placement for accurate fuelling control and crisp throttle response
- SUS304 stainless steel construction resists heat, corrosion and fatigue
- 7-axis CNC mandrel bends for smooth, round internal geometry and rapid gas speed
- Turbo flange features crisscross and overlapping welds for strength under extreme temperatures

Real performance gains you can feel

- Torque gain: +15.9 ft lb at 3697 rpm
Expect quicker turbo spool, stronger low-down and mid-range torque, and a more engaging top end. The Eddy Catalytic core behaves like a higher cell cat at low rpm for emissions, then opens flow at high rpm with a vortex effect similar to a very free-flowing sports cat.
Engineering that sets it apart
Stone Exhaust reverse engineers the OEM downpipe using 3D scanning to perfect routing, diameter and bend angles. Flow, thermal and pressure simulations refine the design before production. The result is a precision-made, integrally moulded SUS304 stainless downpipe with exceptional fit, strength and longevity.
