DG RCM exhaust on 225DR Tri-moto

[code-blue]

I need some help. I just bought a DG RCM exhaust for my 225DR Tri-moto off ebay. This does not have a spark arrestor on it. I see "SPARKY" or "Cobra" makes spark arrestors but they say they are for 2-strokes. Can I use them? My pipe diameter is 4". Thanks

pics please. and maybe links to cobra or sparky arrestor you are talking about. the only way(s) that the exhaust you bought wouldnt have one is ..someone removed it or its a race only pipe, which would be hard to believe for a 225

It does not come with one new.
