Elliott, it is a reasonably straight forward job. The only pointers I could offer are what I imagine you will be well aware of anyway.: make certain you have the correct sized sockets etc., to avoid rounding off. Use a couple of soakings of WD40 and let it soak in before attempting to remove nuts, especially at the manifold. Be sure the joint at the manifold is seated correctly when you fit the new Converter and do not over torque the nuts.
Good Luck with the job. Best Wishes and Regards, John
