spyro Posted March 14, 2009 Share Posted March 14, 2009 i've got a 93 NA with a kakimoto stainless cat back on it, i've noticed a fairly constant blow on the exhaust and been under the car to see if i can find it but CANT, there are no carbon marks anywhere as per you would get from a hole, all the joints are clean and i cant feel anything either, it still has both standard cat's fitted... i was wondering if there is somewhere in particular i should be looking, as the 2nd cat is covered with a bolted heatshield, has anyone had any problems with the cat breaking down inside the casing ? or if there is a flexi or sleeve joint that could have parted ? any help appreciated, simon Quote Link to comment Share on other sites More sharing options...
merckx Posted March 14, 2009 Share Posted March 14, 2009 Have you had someone hold a rag over the end of the exhaust for a couple of seconds while you're looking for the leak? Quote Link to comment Share on other sites More sharing options...
Rob Posted March 15, 2009 Share Posted March 15, 2009 My 1st cat pipe split, presumably due to speedbumps. You'd never see it from under the car. Try peering down at the 1st cat from the engine bay, plus the previously mentioned rag technique. Quote Link to comment Share on other sites More sharing options...
