    Similar to KTMRIDR's 'Reality Check' , a stock KTM 300 is pretty darn quiet - but no Spark Arrestor!
    I'm sure the thought of 'sparks' is just a red herring - the real issue is noise and the assumption is that Spark arrestors will be quieter.

    Am I correct?

    I found an FMF Q-series muffler (with spark arrestor) for my Daughters RM85, and it's great, if a little long and ugly.
    Now it's louder from the expansion chamber than the muffler.

    The spark arrestor does nothing for sound reduction, but it is a valid concern since it reduces the chance of hot carbon bits blowing out of the exhaust. Noise is the driving factor for sure.

    I don't think making your own screen will do. I know its the same thing but the enforcement people enforcing it are not mechanics and won't know what they are looking at. I would think they would look for the stamp that comes on the muffler. I think it says U.S approved spark arrestor or something like that.

    Or you can try make your own screen and let us all know if you get a ticket. Take one for the team! LOL =D>
