The 1GR-FE 4.0L V6 engine has front catalytic converters built into the exhaust manifold assembly. This performance header system replaces that entire assembly including the catalytic converter. This allows for free flowing, long primary tubes that enhance performance.
When the front catalytic converters are removed, the ECU will diagnose a fault setting a check engine light. These headers are for off road racing use only and not legal for use on public roads.
Note: The stock crush to seal gaskets used in the connections between the Y pipe and the exhaust manifolds should not be reused. These gaskets should be replaced. You can select the “INCLUDE GASKETS” box below to have two heavy duty additional crush to seal gaskets included in your order. Doug Thorley recommends that the stock cylinder head gaskets should be reused and new cylinder head gaskets are not included.
