[bumchin318i]

Gathering bits and bobs slowly but the issue I have is regarding the exhaust manifold with t3 flange and down pipe well the down pipe won't be that much of a problem just manifold is there any other exhaust manifold that will fit the stud pattern off another motor ect ? as don't really want to mess about with the cast one or any one on here that makes them ? Cheers
