Hi, I have an ex police alternator model and from what I believe the left hand exhaust pipe was different on this type, for this year I have just run it with the standard pipe with extra spacers etc to get clearance, the only problem is the silencers don't run quiet symmetrical. For next year I would like to get it correct. Does anyone know where I might be able to get a correct pipe or have any drawings to have one made up? cheers
