so this is the only real hold up, other than the passenger side o2 bung that i have to have relocated. the cxracing down piping is made for 3" outlet turbines, like my t76 on3, but the gt45 had a 3.5" turbine outlet, so this flange you see me holding is going to have to be welded into this elbow so it can be connected to the rest of the exhaust. i thought of maybe dumping it straight down, but the cold piping and wastegate are in the way.
