I've been getting this rattling noise from underneath the car that's getting kinda worst as time goes on. it's just for a few secs until the fast idle calms down. well i finally got under there and found out that it's coming from one of the cats in my bassani modular x-pipe. i'm guessing something in the cat broke free. well it sucks and I'm just venting. hopefully I can order just one of these cats from bassani...

How long have you had them? I bet they will do something for you.

about 7 months. the only problem is I bought the new in box from some guy on ebay. I don't have any reciepts from bassani. who knows though maybe a phone call to them will help.

I hear a rattle from under the car on cold starts but I think it's just the connection between the midpipe and headers.

Sorry to hear that. Are you sure it's coming from the cats and not the heat shields?

BTW: How does that setup sound? I have the SLP LM's and was considering the Bassani Modular X. Did you have the SLP's before you installed the Bassani? If so, what was the difference in sound when adding the Bassani?
