so i picked up a new bike the other day, and after un restricting it all up and pulling the little baffles out of the exhaust i still think it sounds a little wimpy. is there any other mods i can do to the stock muffler to open it up? i have also been looking into a slip on exhaust but am not a big fan of how long all of theyre mufflers are. so my second question would be will a slip on for another bike fit? say maybe for a yz450F?
