I really love the dual exhaust treatment this driver did, but I have a feeling it's not a straight up bumper replacement. Since I'm in the US, I am not familiar with the Astra J GTC OPC/VXR at all, and I can't tell from the pics I've looked at if the rear bumper is a direct replacement or not. Has anyone else updated the look of their Cascada to dual exhaust, or have any suggestions on the bumper swap?
