The part is used to bypass the catalyst from the exhaust to create a ‘Decat’ system. Eliminating the catalyst will greatly enhance the gas-flow and the performance, adding significant Hp to your vehicle by removing the density of the catalyst in which exhaust gases are pushed through. - This product is intended for motorsport use only and requires Stage 2 ECU remap.
