650C SERIES UPGRADE (NOW INCLUDES CURVE EXTENSION)

Stock Code Length
As temperatures can exceed 650C on EGR-DPF motors, we have improved this series to protect against discolouration from temperatures exceeding 650C. This is achieved by incorporating an inner sleeve with the AdBlue Upgrade to the full length of the stack (including the curve). This creates a multiphase proprietary system that prevents the chrome discolouring and provides an internal Armour to the corrosive effects of Urea Re-Agents. Available in all reduced sizes and styles in the Silverback range.

Join the Silverback legacy and become a leading beast in the pack!
