Ultimate Racing Downpipe rattling?

Does anyone have the 3" UR downpipe and their high-flow cat or test pipe attached to a 3" exhaust with cams installed (HKS 272/272)?

Ever since I've had my cams installed my downpipe (I think) hits against my oil pan and it sounds like **** everytime I rev.

Anyone else have this problem?

Since Ultimate Racing seems to be of no help at all to me everytime I ask them about it, they don't seem to want to do anything for me.

Anyone recommend any other downpipe? Or what should I do?

I have their downpipe and HF cat, i thought my dp was rattling, turned out to be the Cat. Ended up taking it off and cracking the converter with a hammer and beat it out.

No more rattling after that!

Cracking the actual cat? I'm confused as to what you did specifically...

I had their test pipe on there too and it still rattled, so I'm guessing it's their downpipe.

The honeycomb inside the cat will crack and break under pressure.
