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
