lyzic Posted July 19, 2010 Share Posted July 19, 2010 Hi, So I bought a bosal exhaust and bosal resonator to replace my rusted out stock stuff. I got it taken off fairly easily, except for one problem which is mystifying. Where I bolt the main exhaust on, just after the O2 sensors, there are 4 bolts. Are these bolts, or studs? Are they part of the original exhaust, or do they come off? I had to cut one off flush, and none of them won't move. Won't even budge a little. They're so rusted I can't even tell if they had heads on them to fit a ratchet anymore. I think I'll have to cut them out and put in bolts anyways, but looking for an answer so I know what I'm dealing with first. Thanks! Link to comment Share on other sites More sharing options...
180sx Posted July 19, 2010 Share Posted July 19, 2010 Just cut them all off and be done with it. Link to comment Share on other sites More sharing options...
skulptr Posted July 23, 2010 Share Posted July 23, 2010 they're studs, like lug nut studs. i dont recommend pounding them out, you can (in my case) shock the manifolds to the point of breaking. i just heated mine up and pressed them out. once theyre red hot, they move like nothings holding them in.
