spark arrestor

[brokeass]

Is there a spark arrestor for the ESR trx5 centermount pipe that will pass CA forestry regulations? looking to go ride at Gormon Hungry Valley, but I have no idea where to find a spark arrestor for my 'short stinger' silencer

thanks,
Zach

ESR sells a spark arrrestor centermount silencer but this is not guaranteed to pass the noise limit. I have one on mine that still runs around 105 db. Your best bet it to put a turndown end cap and put a screen behind it.

Thanks NorCal! I went ahead and called ESR, they recommended a sparky cobra for 2 3/4 inch diameter silencer and mentioned that esr wants to make there own spark arrester end cap in the future. Anybody got a spare sparky?
