    I recently bought a 2005 525 EXC that needed some work and am doing the work myself.

    The bike was so loud so i pulled apart muffler and found that there was almost nothing inside - just a short baffle/plate with many big holes drilled in it.
    No longer/small diameter baffler and no fibreglass matting.
    I have posted pics of whats inside.

    I have searched everywhere but cant find any photos of what should be inside, so I can rebuild it.

    Can any one help?

    He has an extra smaller diameter baffle pipe which I dont have, which is what I had guessed was missing, but oddly the microfiche doesnt show this part for my bike.
    Seems like a good mod.

    So given that I want to make it quieter than stock, I may do as he did and remove the existsing large diameter baffle and add the smaller diamer one for the full length.
    Ir will it be sufficient to just add the missing baffle that he already had that i dont?
    Thoughts?
