hey this is for the Gixxer guys I have a 09 gsxr 600 I know this probaly has been said before and I pretty sure I seen a thread on it. But after 1 hour of searching.... So will a Will a OEM 06-07 muffler fit with a cat hack? Because I'm going to do a cat hack for my yoshi 07 and just incase the police pull me up it would be nice to just put on a OEM 06 muffler/cat to do the tests. Just want to know if it will fit and also i pretty sure i read some where it comes pretty close to the fairing and might melt it. Oh and any body have their muffler lying around??? Anyway sorry again and cheers.
