Don't think auto vs stick matters, but are you going to replace the cat converter, too? If not, going to 3" will mean a bottleneck at the converter. The stock size is either 2.25" or 2.5" (I forget). I don't think 3" will hurt, just question whether it'll help.
I assume you're doing a header when to add turbo.
