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?
