hey guys, I'm looking for someone who has bought the exhaust stated above. I recently bought a used one from a friend and was looking to take the spark arrestor out but, when I pull it out I don't have another ring to put back in there to cap the exhaust hole. I looked around on the internet but did not come up with anything. I put the screw back in but I'm thinking there is suppose to be another ring to put back in. I was thinking about just cutting the screen off the spark arrestor and using that because I will probably never need it. Thanks for any imput.
