one of my buddys has an 01 6 spd and when he shifts into 6th there is a faint grind what could be wrong with it?

i also agree, could be a syncro or heck even a bearing but i lean more towards the syncro. i say drain the tranny and see if you see any metal flakes in the fluid

Yep...sounds like a sycro to me as well. Drain it, inspect it and re-fill with fresh fluid!

Racing a 6speed
maybe he's not shifting into 6th right too,sometimes if a person times it just wrong it will kinda grind a little.

I've had Amsoil in my tranny for a while,still works good.
415k or so on it now.
