i was just wondering, is there a way to make my YFZ louder without buying a new exhaust system?

Take out the baffle. That will change the tone. Also, I don't know if people have done this on the 450, but I have heard of Raptor owners taking a long drill, and putting some holes in the baffles of the muffler. I haven't done this, but I am sure it will make it louder. If you want really loud, take off the muffler. That will get people's attention. Otherwise, there isn't much you can do if you don't want to get an aftermarket exhaust.

Baffel out.. a lot louder.. if you want faster from there jet and air filter it!!!!!

 

Take out the baffle & airbox lid your going to get louder and add about 2 hp
