Default Full LT exhaust questions

I want to do a full exhaust job on my 97 t/a, but have a few questions.

1) I know LT's are the way to go, but how do i do away with the egr?
a) do i just close off al of the hoses leading into the egr valve?
b) what about the computer? Must i have someone tune it for egr delete?
2) I think the pacesetter LT's have holes for the O2's, but what about the post cat O2?

I think I want to get the pacesetter LT's, y-pipe, and the loudmouth catback. Besides the mounting hardware for the loudmouth, and O2 extensions, what else do I need to complete the job? Thanks, -Chris


BTW: I have no intentions of running cats.

1-a) Just get EGR block off plates

b)Yes you will have to get someone to tune the egr out otherwise you will get an SES light

2)Prolly have to drill and weld in an O2 bung then run an O2 extension

With LT's you cant run CATS, at least in the stock location. I would do just away with them and get it tuned for not cars and no rear o2's, its easier.
