A friend of mine bought a 08 yzf450. I read articles about this new muffler that it has, and I was wondering about a spark arrestor. When they test for spark arrestors on the trail, they just stick a rod into the exhaust. With this new Muffler I don't think that the rod will pass through the muffler, but it dosn't have a spark arrestor. Would he be okay to ride on the trails without modifing it.
