L4V15 Posted November 25, 2011 Share Posted November 25, 2011 Hi. I've just noticed that both my cat converters have holes in them surrounded by rust. Through some of the holes you can see the wire stuff just about. I have no fault lights on on the dash. Just wondering whether or not these need replacing or are they still ok to use, if so how long are we talking until they should be replaced. Also just out of interest, does anybody know the size of the standard tailpipes, just wondering whether the exhaust is standard. Just got the car you see. 2004 350z. Thanks Steve Quote Link to comment Share on other sites More sharing options...

Thanks Steve My cats were in the same condition, had to replace them as they began to rattle at certain RPMs. Show us a pic of the tailpipes, we should be able to tell ps - to the forum mate!

CMR Posted November 26, 2011 Share Posted November 26, 2011 It sounds to me like the heat shields around your cats have rust on them, not the actual cats themselves Quote Link to comment Share on other sites More sharing options...

L4V15 Posted November 29, 2011 Author Share Posted November 29, 2011 Ideal, cheers for the responses. I've checked and it is just the heat shields luckily. I had ordered high flow cats aswel after looking under the car in the dark. Now got a refund before they had sent them luckily. And yes the exhaust is standard, im sure of it. There are pictures in my profile I believe. Thanks Quote Link to comment Share on other sites More sharing options...
