I do have a powerbomb header. All my mods can be ssen if you click the "My Bike" link in my signature....

 

I have the stock Q4 insert that came with my FMF, never used and brand new. I went with a smaller diameter insert to make things even quieter. It has no numbers on it but can take pic if ya think its the one.

 

Yeah? That would be a great if you could take a pic. Much appreciated.

So this part came with the exhaust as an extra piece (some kind of special deal at the time?) or was it inside and you took it out?

Thanks!

Good news. My eBay alert notified me of someone selling one. Lucky me, there were four or five sellers. (Odd...all around the same time) One had shipping for $11 or so. Nice!

Maybe FMF shipped out a new supply. Anyway, will see how this works in a week or so.
