   could always get a tube with a silencer mate will make it quieter without power loss.

   Would probably lose about 2-4bhp, barely noticeable
   
   Technically would be a 're-cat' lol
   
   Plus with a CAT on it would pass an MOT
   Am dreading the ballache of recatting mine for the MOT, right pain in the arse

   anyone know of any sports cat that will actually pass an MOT?
   all the ones ive looked at wont get the emissions down enough.
   
   only thing i can think of if you want cat on and MOT pass is to give ya engine a really lean air/fuel mixture. might get too hot tho :/
