Hey guys been a little bit since I've been on. I hope to install the new UIM soon...there will be pics. Anyways onto my problem. My Cat is making a rattling sound, mostly when it'* cold. This problem worries me because I am not sure if my car will pass inspection when it comes time. I talked to a guy at a local shop he told me he thought the problem was that the catalyst was loose or something but he had no idea how it would show up when they check emissions. I wouldn't mind replacing it to ensure my car would pass since I could put on a high flow cat and get a new downpipe too. I don't really have the money right now, but it would be an upgrade and ensure I would pass so I could come up with it. What do you guys think?
