    The join, near the rear axle beam, between the intermediate silencer and backbox can be either sleeve or flange.

    Sleeve is where one pipe just slides into the next and is clamped tight.

    Flange has an oval bracket on each pipe and the two flanges are bolted together, with a gasket in between.

    On Astra-G it's very difficult to tell from model or chassis number which is fitted - the only sure way is to look underneath at your existing fitting.

    If you're replacing both sections, it doesn't matter whether they're flange or sleeve as long as they're the same.

    There is a converter available, but it only works one way (and I can't remember which!).

    The linked picture shows flange welded on the centre pipe, far end, and a floating flange on the backbox inlet.
