i have read on the depot that both hooker and kooks do. hooker though seems to have some leaking issues every once in a while.. but i have heard very little on kooks in general, good or bad.
my understanding is that bassani midlength headers allow for the work as well, i need to confirm this with the company, but have seen a few posts that say the bassani's alow for the clutch/tranny work
