It can be done, but be sure the chrome plating firm will do the pipes first. Any dirt, soot, oil, etc., that is in the pipe might cause them to decline the job as it will end up in the bath and they won't be too happy about that. Also the stuff will effect the outcome of the job. When my father restored our Shadow he had the pipes rechromed. We tried to clean them inside and out as best we could. The chrome shop accepted them and the job looked good. When we fired up the bike the first time after the rebuild a huge blister appeared on the pipe. Obviously they weren't as clean as we all thought they were.
Few years back I bought new pipes and silencer from the club when the the baffles blew out of the old silencer.
