Fisch Moto Dirt Bike Spark Arrestors - Product Showcase 

Great looking product. I was looking at a 250 XC and keep it low budget. This would be the perfect answer to not buying adding a USFS approved silencer.

So I’m between this one and the fast way. Does anyone have insight?

Of course you know about these, I’ve been looking for a drop in one for ages, finally heard about these and a quick check on RU-vid and it revealed Jeff approves, good find.

Perfect. I was waiting form them to have the USFS stamp on the ring and it looks like they do now. Buying it now.

will this work on a 2005 yamaha yz450f stock pipe

NICE!!!

Wish I'd have known about these 2 days ago when u made my order...

Will they fit inside the lexteck sp1 baffle for my 125 4 stroke super moto as I need one in order to go green laning

Thanks Jeff!
