sc_dragon Posted May 9, 2009 Share Posted May 9, 2009 Hi all, When i put my car on the r/r today the guys said there was a foul smell coming from the exhaust hence they said it could be the cat(s) a) How do i find out which cat needs replacing? b) Will the car fail the mot by removing the first or second cat? Cheers Quote Link to comment Share on other sites More sharing options...

wilson4347 Posted May 9, 2009 Share Posted May 9, 2009 I believe you only need one cat for the mot Quote Link to comment Share on other sites More sharing options...
sc_dragon Posted May 9, 2009 Author Share Posted May 9, 2009 I believe you only need one cat for the mot Does it depend on which one is removed, for it to pass? Quote Link to comment Share on other sites More sharing options...

Benjy Posted May 10, 2009 Share Posted May 10, 2009 I've got the first cat if you need one. Mine had the 2nd cat "modified" slightly (the cat was opened up and internals removed) and flew through an emissions test with the first cat in place.

sc_dragon Posted May 10, 2009 Author Share Posted May 10, 2009 Thanks for your replies. Ben SZ-R (btw, your car was looking very nice yesterday!) or Clueless - i might have to take one of you up on the offer, if i find out it is faulty. In general - how am i meant to determine which of the cat(s) are faulty? Cheers Quote Link to comment Share on other sites More sharing options...
