Hello everyone. Just the forum and looking for some advice. I have a 54 plate Outback 2.5 petrol (non turbo). Last night whilst driving, the straight pipe that connects the midbox to the cat has sheared completely off of its flange. Is it possible to get a new piece of pipe with the flange already on it and then cut into the pipe and fit a coupler sleeve? If this can be done, does anyone know where i find out the diameter of the pipe required? Thanks. See pictures attached.
