there only 270's paul.... also it sounds like a pain in the arse on the street tis all i will say lol
have also been discussing with paul my exhaust housing size.... atm ive got a .81 but the .96 housing seems that it may have been a better option... the only problem is to the manifold i have is single entry not twin entry so im gonna have to check if they make a single entry .96.... will also have to get the housing made to suite my wastegate inlet pipe... ahhh more mucking around
