I am a fan of Crawford.. Well I was.. I put the high flow cats on about 10 months ago.. Then a couple months later I put on the Nismo exhaust.. Wow it sounded great. Then about 3 months ago I noticed a wierd sound. Like an air leak. So I brought it to my mech and when we put it up on a lift we noticed a nice crack in the crawford cat right on the bend. So I call Crawford they were realy nice and sent me a new set.. So I put them both on and now for the last 3 weeks my cars has been running bad and I notice some extra noise. Im bring it back to my guy on Sat. I think its the cats again.. Is there an issue with these cats? Im not sure what to do as im not going to keep paying this guy to replace my cats after they crack every month or so. It made me soo sick I dont even want to drive it till its fix. So for the last 3 weeks I drove my car 2 times.. Please help! Is there any other cats that dont have this problem with the Nismo? Or maybe I should just go test pipes...

 

I'm sure you're going to love to hear this, but you're the first person I've heard of that's had a problem with the Crawford cats.
