My 96 KX 250

In my personal experience, the stock silencer is very quiet compared to most, you can buy slip on spart arrestors from Sparky (denniskirk.com) or pro circut spark arrestor is quiet too. I read from a fellow on here (Doordie) they make a silencer called a hush puppy. But never seen it here in the states.

Oh yes, repack the silencer you have, it makes a huge diffrence in noise and gives alot more power. On my YZ250, the pro circut is the quietest. I was thinking 500, but for a 250, I believe it is the quietest so far as I know of.

The Hush Puppy is from the 1980's,dont think I've seen it around since.FMF Q-series, Pro Circuit type 296, or as gowen said the stock silencer with a  "Sparky" add on spark arresters should be quiet.Use high temp silicone on all the joints and a wrap around aluminum or carbon fiber pipe guard will help cut a little noise.You could also fabricate a tip for the end of the silencer that aims towards the groud ,that will help.Try repacking the stock silencer first,if its still to loud dont get a spary (its not going to cut much noise),instead try the FMF or P.C. silencer and go from there with the other ideas.

Thanks guys.  The silencer I have, I was told was relativley new. Like last year purchase. I will try repacking it and see how that works. Then I will put some research into fmf silencer as I have an fmf fatty gold pipe now. Why not remain constant? thanks
