ERZ Performance High Flow Cats, Install and Review Thread

help! first day driving it for a lengthy period and ive noticed a rattle? i went down and tightened the extra O2 bung caps, and now the idle rattle is gone. while i was down there i knocked on the hfc's and noticed another rattle somewhere in the H-pipe. i removed the heatshield clamps, and out came a few rocks that were rattling in there. no more rattle...or so i thought

started it up and here's another rattle! see the below "video". its more like a sound clip, but theres a weird noise. ive loosened all the bolts and re-situated the gaskets, and retightened them...yet im still getting this disgusting sound! its pretty annoying and ricey sounding. could it be a leak somewhere? should i buy new gaskets?
