It depends on where you're riding and how legal you want to be. If you're on public land, yes, you should have a spark arrestor. If you're riding MX on private tracks, no, in most cases you don't need one.

To be legit, you need to have the USFS Approved stamp on your spark arrested muffler. This can be attained by buying a spark arrested slip-on or a spark arrestor end cap sold by companies like pro moto billet at
