When I get my turbo, can I keep my stock ITR exhaust for a while? I know the rule is to NEVER go smaller down the line of the exhaust (ITR is 2.25" w/ several 2" restrictions, and dp is 2.25"), but I wanna eventually upgrade to something nice. Somethign I can't afford right now.

There isn't any HARM in keeping this smaller exhaust on for a few months, is there?

 

As long as the boost does not creep you will be fine. It will be OK.
