Good afternoon, what you will need to remove is the majority of the exhaust system. First the front resonator and all the exhaust from there back will need to be removed. Then you will need to remove the entire left side catalytic converter assembly from the manifold. Then you will need to remove just the extension pipe from the right side catalytic converter and leave the right side catalytic converter bolted to the manifold.
The left side pipe is a one piece design with the catalytic converter made to it....the right side is a two piece design so just remove the lower portion.
