[Fire Escape]

That is discouraging! I just got a(nother) "turn down, quiet, SA end cap from FMF. Having looked at my existing one with the big hole through the center I figured it was either the wrong insert or modified - Wrong, the new one is just the same. How can you have that big of an outlet and still call it a Spark Arrestor? My next step was goin to be to restrict it more like in the above picture but it sounds as though that isn't going to help much.
I see that Pro Moto has an end cap and insert but I think that it is for the Kreiger, anyone know what size, model, part number or other way of identifying the FMF "Q" is that most of us ended up with? Mine came from the dealer with it, don't believe he changed it though. I was going to contact Pro Moto to see if they have anything to help the "Q" but figure that I might need more information to give them. Tried FMF but haven't heard back.
