It is not that bad. You are going to have to remove the exhaust manifold heat shield to see everything and also remove the intake air duct at both ends. There are a lot of vacuum hoses and fittings there so take a few pictures.

Be careful with unbolting the catalytic converter pipe from the turbo housing. I like to spray PB Blaster on the three nuts and give them a few treatments about an hour before trying to crack them loose. When you do finally loosen the bolts, use a good socket and give it a quick torque to break them loose. Cheap or loose fitting sockets will round them off and then you're stuck.
