Need help on finding out which manifold i have

Hi peeps,

I have acquired a Jasma JDM exhaust manifold for a civic from a member off here but it doesnt fit my ek which is a d14a4 ( he said if i had any problems he would sort something out so i tried to contact him in everyway possible but no answer so i'll be avoiding him). So im thinking its a b series manifold to be fitted with either a uk or jap cat? whichever is longer because it is too short for my ek when i tried to fit it. Once i know what civic it is for, it will be up for sale

If anyone can help that would be brilliant

Thanks
