Hi, just thought of something....
is it ok to bolt on a .48 exhaust housing onto a std RST T3 with its .32 housing? Is it simply a case of unbolting new one, splitting it and bolting up the new housing/onto manifold and would the exhaust flange bit (forget its name) bolt onto it np? or is their ANYTHING needed in swapping these parts over? bigger exhaust wheel or ought?
