Visit Korider.com and go to the 250 forum and do a search. I posted pics many years ago.

Wrong! Adding holes to the muffler releases back pressure. This can be good or bad depending on the intake and carb setting. Adding an aftermarket muffler is worse then drilling holes in the baffle. Also the muffler exit hole is still the same diameter so there is no change in pressure.
