2019 yz450fx spark arrestor

Recommended Posts

I just picked up a 2019 yz450fx. I have been looking all over the web, trying to figure out how to add a spark arrestor insert without spending another $400 buying a new silencer. Anyone have any ideas.

What is the size of the exhaust outlet? I have two spark arresters that can be used. Would have to tap a thread to hold it in place

I think the lexx spark arrestor end cap for the 2016-18 years may fit. I'm ordering one to try it out, Rocky Mountain says they're not sure yet, but the silencer's look the same.

I’ll look at the exhaust hole tomorrow but I was hoping there was something that is actually made specifically for the 2019 yz450fx. But it seems like all the spark arrestors are not for the stock silencer
