So, I have 2000 superglide. Ive be n looking at exhaust on a few different forums and have found many but they are for the 06+ models. What is it that makes them different and if I plugged the o2 bungs would they work? Also same question for the seats..... What makes the 06+ seats not fit on the earlier bikes?

 

06+ has a 6 speed so the mounting bracket is slightly different. 06+ systems won't just "bolt-up" to your 5 speed. It's not hard to make it work though.

 

aight thank ya sir. I was wondering as the heads and cylinders all swap between them.
