Will A ROSI cat fit with a JANSPEED exhaust **
.....
I am geting a janspeed supersport cat back exhaust soon and need to know if a rosi sports cat will fit with this system. Do most cats fit most exhausts, or do you have to be spesific like a janspeed exhaust with a janspeed cat for example?? many thanks !!!!
