[QUOTE="Riddick, post: 16635442, member: 143188"] It's more than likely part of your exhaust, I highly doubt its your catch can. It could be anything from a loose fastener, loose o2 sensor, or a bolt barely rubbing the body. With your engine cold crawl under your car and use your palm or a rubber mallet to hit your exhaust, check at headers, mid pipe, and over axle pipes. There should be 0 noise, if you hear any rattling what so ever there's your issue. I guarantee its false knock, especially since your on ethanol. On my set up I had an issue with the fasteners kooks sent me. They came with locking retainers for the bolts so they wouldn't back out and they rattled like crazy. Removed them and that fixed my issues. Also, keep in mind your exhaust moves with your engine under load. If any bolts are close to the body there is a good chance they are hitting your body under full load. Best of luck and make sure to report your findings back to us. [/QUOTE]
