arrester

I want to do some mnt riding just wondering

Hi, anyone got the part number for the above. My bike came without it and I need to quieten it down. The local KTM dealer is clueless. Thanks

I have the 05 fc 550 and was wondering if any body has the stock spark arreser that is in real good condition that they might want to sell? Thanks,

anyone have any data or opinion as to how restrictive this muffer/spark arrester is? would an after market Big Gun provide any improvement in power or have any thermal bennefits

I lost my spark arrester the other day - not sure what happened, but the screws that hold it on, are still there, but the arrester is gone. Where can I get a new one? Also, I would like to quiet this thing down a little. It has more than enough power for what I do, but is a little loud...
