I just had Lancerman install some aftermarket stuff on my 03 Evo 8. So I have the following stock stuff:

-Stock Air box with a K&N Filter (unfortunately does not have the securing bolts)
-Stock intake pipe
-Stock upper & lower IC piping
-Stock exhaust (welded cat-delete from the previous owner)

I have not thought of any prices, just let me know if your interested. If not, free bump and GLWS.
