The group includes seal rings and copper washers for flange joints, brackets and U-bolts for the suspension mounting, clamps that draw pipe joints together, plus lock nuts and plugs. When replacing an exhaust pipe or muffler, it is worth checking the rubber on the brackets and the seal rings at the same time – worn mounting puts unnecessary strain on weld seams and new pipes, and a dry seal ring often starts to blow shortly after an incomplete replacement.
Always check the flange dimensions and mounting against your car before ordering, so that washers and clamps match the pipe size on your specific B234F version.
