Greetings! First post on here since picking up my Softail Slim a couple of weeks ago. Lots of good info on this forum but I haven't been able to find a direct answer to the following question so I am hoping someone can square me away on this. I want to add a set of V&H Straightshot slip-ons to my Slim in order to help her sound better. My dealer has told me that if I do that, I also have to add an intake kit and have them tune the bike. The place I'm buying the slip-ons from says because the bike is fuel injected, I don't have to add the intake or do the tune. Eventually I will probably want to do the intake/tune but for now I just want to improve the exhaust sound. Can I add just the slip-ons without causing problems or damage to anything else on this bike? I want to make sure if I only add the slip ons that I don't have any mechanical problems like a burnt piston from the bike running too lean or that I don't cause any decrease in performance. Thanks!
