charlieboy2608 Posted March 3, 2019 Report Share Posted March 3, 2019 Just been reading the Bentley manual for the above,which I believe is based around the American spec vehicle-these have warm cats and main cats (total 4) to comply with american emission laws. My question is do the UK spec vehicles also have a total of 4 cats?-If so my "S" seems to be missing two........ Link to comment Share on other sites More sharing options...
