While reading some older posts, I found Gray mentioning that the stock exhaust on an 08 yz450f is not that good.

 

Who makes the quietest slip on muffler for the yz?

If I want to make do with the stock exhaust for a while, what is the cheapest way to add a spark arrestor?

Quietest one I know of for sure is the FMF Q4.

 

Both Pro Billet and Dr. D make spark arrestor end caps for the stock can.

I can't speak for the others but my lexx mxe is pretty quiet.
It comes with a removable spark arrestor and a race tip.
I tried it with the arrestor out and I can tell there's quite a difference in power but it's just annoyingly loud...
You can tune it how ever you like. Plus, it's only $200....

I saw some of those while browsing ebay, Amazing how expensive some of the 4 stroke mufflers are! $200 sounds good compared to the cheapest FMF pipes.
