16v exhaust manifold help

looking into replacing my home made manifold for a proper one and just wondering if anyone has had or know anyone who has had a hottuning manifold off ebay?? one are they any good and two do they fit on to the standard exhaust??

Hottuning ones, sometimes require bit of modifying to get the final finish right so gaskets line up etc but aside from that are good an half price of supersprint ones., you would have to look st what system you already have to dee if it will fut. You nay need to get an adapter, easily available if you do
