I have a stock 91 EVO Electriglide with a cracked y pipe. I a considering putting on a true dual system. My problem I'm having is finding a manufacturer for my year bike. The shop I deal with found one, but it is for a 95. We call the manufacturer ((Paucho) and they said it should fit my bike, but my slip ons will not fit. So I will have to get a newer style slip on. We also called HD and I can still get a new y pipe for almost $500.00. I'm just wondering if it's worth my while tring to weld the pipe or just replace the whole system with a true dual. The shop assured me the could weld it with success. I'm not going spend that kind of money for a new y pipe, when for only a couple of hundred dollars more I can get a complete true dual system. What are the advantages/disadvantages of a true dual system? Of course it would be a lot cheaper to just weld it (free), but the shop said I would get a noticeable performance improvement with a true dual system. They are good friends, so it's not that they are trying to make a couple of bucks. I know it's an old bike, but it runs like a top. It seems all of the manufacturers only go back to 95. I was wondering if anybody else with such an old bike had the same issues. Any help would be greatly appreciated. It has 31,000 on the clock. Thanx Bus Driver.
