i thought it to be 54mm... anyways, i have one next to me and i will measure. there's a lot of misinformation in this thread. 50, 53, 54, haha. somebody's wrong!

but... a larger tb on a 99+ isn't worth much. it is worth a few ponies on a 94-98 but that's not your problem. getting a p/p intake with bolt posts removed can really get some top end out of her though. (12-17rwhp depending on quality).
My stock one was a 53 mm and I checked it personally.
