Rattling noise

I have been having rattling noise which i thought was coming from the factory sport exhaust. I took the PSE off and installed the original exhaust and the rattling was still there. I checked the PSE for anything loose or broken with soft hammer with light taps and shook them around and found nothing. SO now im thinking it the catalytic converters. Can someone post the part numbers for both left and right on a 2002 996. Thanks

Hi Loren, took off cats and there is nothing loose but when you look through them it looks like the honey comb has moved position a bit. When the cats were on the car when you tap them you can here a can like noise but when the are off you cant hear it. So im leaning towards the cats because after putting on both PSE and stock exhaust the sam rattling noise is there coming from cats. I did have cat from another 996 go bad that u can visually see the honey comb moving around. This car has 156K on it. Noise not coming from motor so thats good. I plan on replacing cats with both new ones .

You really don't want it to be a cat...

I also had a similar noise and it was as 100plus suggests, in my car it was the heat shields, very easy no cost fix for mine.

Check your parking brakes or heat shields. I have the exact same rattle and it was coming from my parking brake.

Cheers

These were the ones in the rear left guard [fender] on my car, they were quite loose, I just pushed them back into the space, not sure how they are held in but they seemed to click into place. That was 6 years ago, no noise since then. If you hit the lower section of bodwork in that area with your hand you may be able to duplicate the rattle if that's where it's coming from.
