I just bought this to be on the safe side. I'm debating about putting it in for on the trails, probably end up using it (b/c of DNR). It says it only takes 1.5db off, nothing major. I'm very happy with the quality of the screen and how it's held together. Haven't tried it out, but overall I'd rather be safe than sorry ;-) Would recommend buying if you're debating about purchasing a spark arrestor. Rather be safe than sorry
Once shipped correctly (FMF packaging not Dennis Kirk) item was perfect.
Good product. First units sold in 2 similar package, one had wrong part. I was charged for replacement even after shipping wrong part back. I purchased 20 dollars in extra items to install wrong part before I compared to the other, PLUS the added DK charge.
