I have a 2003 DRZ400E....I purchased a 2004 DRZ400S subframe and passenger pegs. I am sure this question has been answered but I:confused: cannot find the thread. What more will I need to do to swap out my E subframe for the S subframe? Will I need to purchase an S rear fender or will my E fender work? I have seen references that I will need to do some mods to the exhaust but I haven't seen specifics. Is it very difficult? I am sorry if this is a repeat question. Please help. Thank you.
