ITR header on b16a swap??

If I put a ITR header on my b16 would it go in between the oil pan and modified crossmember or will the whole thing hang down? My 4-2-1 header hands really low already but its for an ls which has a 8mm higher deck hight from what I understand. I dunno, if i can run a itr header with the same clearance ill take advantage of it cuz im running the 4-2-1 which is way low since its for an ls.
