well changed the manifold today, took 2 and a half hours to get off and new one on in place ready to bolt back together, have to say wasnot as bad as i had expected, yeah theres a lot of jiggling and "rugging" as we call it where i live, but it came off, not to badly, i did have the help of a mate, but no fancy tools,
i bought a second hand unit from james at jms tunning, i think i am going to get my old one modified, so that there is only one flexi, where the pre cat should be, so that if i breaks again, it can be welded up with a new flexi in place, with out unbolting any sub frame.
