hollandsd 0 Posted February 17, 2010 Report Share Posted February 17, 2010 Hi Guys i have a 97 Highline and the cat is blowing, i was wondering of there are any known areas of weakness in the cat where it may leak from.I havent had a chance to look at it closely yet.Will a GTI Cat fit as standard or is the pipe dia different.Any Help would be appreciated.Dan Link to post Share on other sites
golf harris 0 Posted February 19, 2010 Report Share Posted February 19, 2010 i had this problem with my cat( 97 vr6) blowing ,look at the rear of the cat (exhaust box end) and there seems to be a hole which looks like there should be a bolt in it but on mine it was missing hence the blowing i just plugged it with a bolt of the right size for the hole.have a look mate might be your problem too?
