Upon Googling the pipe, it seems to be a typical FMF pipe, but I'm not sure if it's for bottom, mid, or top end power. Yes you'd have to rejet if you run that pipe, same as any other aftermarket pipe.

And while you're at it, put the K&N airfilter on and take the airbox lid. Do all of this at the same time so you only have to rejet once.

Ok ive never jetted before where would i start on sizes and what jet should i change and also when i go to the store what all sizes should i get
 
*Wow, I just realized that's only a silencer even though you stated that fact many times. Typically it's not needed to rejet for just a silencer. Be sure to check your plug though.
 
As for jetting, I'm pretty sure you go richer on the main jet. For numbers though, you'll have to wait for a pro. Jetting is something I'm still trying to learn.
