3rd gen Yoshi muffler fit a 4th gen?

I see a 3rd gen Yoshimura muffler posted in the classified section of VFRworld. Anyone know if that will fit a 4th gen? I looked up 3rd vs. 4th gen stock Honda mufflers, and they have different part numbers, so I'm not sure . . .

 

Not that this is to much help, but pretty sure they are two different animals, close but.

 

Yeah, looks like 2 different animals. Oh well . . .

 

If you can get the collector too then the Yoshi pipe will work. The 4th gen collector will bolt up to your 3rd gen.
