I thought the consensus was the screen at the tip was more of a dissipator to keep from melting the stock turn signal. I'm sure it helps with noise and may also serve as a secondary spark arrestor. It might also add enough restriction (coupled with the inner restriction) to run stock jetting almost safely.
I think the real spark arrestor is a Krizman (sp?) type way down in the muffler.
