[Chris2007]

Hi there i have a Yozzasport Race Ragnotti Exhuast system, and im after a cat for it for the MOT and too tone it down a little, please would someone be able to tell me which cat i would need for this system? and if it would make much of a difference to the sound of it ?

whats a spacer? and where would i get one?

yozza, you need one because the 172 cat has a sticky out bit that won't fit the YS centre section

you have any idea how much difference it will make to the sound?
