^ i believe most hfc rattle, thats why you gotta get an engine dampner...
the older crawfords were know to rip and tear where the brackets are (under the cats) and i believe an engine dampner will help with that also

Fast intentions dont rattle, thats what i heard.. they dont have any heat shield to bother with..and they have great clearance.
I have Crawford and no, it doesn't rattle .... how do they do inspection in NYC? didn't they just test the *** from your exhaust (that's what they do in Cali)? It should pass if that's the case (hfc still has the catalytic).

They have media in them that is supposed to scrub the exhaust. They are filled with a metal catalyst, usually platinum, rhodium and/or palladium. That is why the cost so much.

They are made of ceramic cores or metallic cores, and the metallic cores are rolled, but still in a honeycomb shape/pattern.
