Does anyone knows how to remove the baffle while keeping the spark arrestor on CRF450X 2014?

Welcome to the site !!

The baffle on that year is welded on i believe , so its a lot harder to remove than the older models , and takes quite a bit of work to remove with any success , what is your reasoning for wanting it removed ??? , you might be better off just finding a used 450R muffler (i believe 05-06) will just bolt on) and just get a Pro Moto Billet Endcap on it (thats what i did to my 06 which is basically the same , as 06-14 take the same muffler) , or if you can afford it , just get a aftermarket muffler (just the muffler and mid-pipe , not the entire exhaust system) , if your on a real budget , you can always find used systems on eBay
