I have a 2010 super glide custom. 8,000 on the clock. Been out a few times with her this season and noticed this week quite a rumble from the pipes that I don't think it sounded like before. Don't get me wrong.....I like the sound but it is the stock exhause system and I am thinking something may be wrong. A buddy told me it may be a problem with the baffles because I don't see or hear any exhaust leaks near the motor or anywhere. Guys I don't know the slightest thing about the machanics and that is why I love this site.....plenty of knowledge and skill out there to draw from. My question is do you think there could be a problem with the baffles with only 8k on the clock and if so will it hurt the motor? It is under warranty of course but will I look stupid bringing the bike in cuz it got louder?!?!?!?
