I was at an auction the other day and walking through the yard of stuff was a set of factory 79 exhaust pipes. I couldn't believe my eyes as the auction flyer said nothing of motorcycle parts being available. Well, I just had to leave with those pipes because I like the look of original pipes and my first acquired 79 bike didn't have original pipes on it when I bought it a couple months ago. I was able to get the CBX pipes along with an original set of pipes for an FX Harley and a set of drag pipes for the Harley. I got all 3 sets for $475. I feel I did OK. Still can't believe my dumb luck.
