I just picked up a clean 2005 V a few weeks ago. The other day the CEL came on so I stoped at autozone and it came back with a P0430 cat bank 2. Just wondering if I should go with high flow cats or what. Im a noob so take it easy. Thanks!

Thanks for the reply. So it is either running too rich, lean, or had a missfire that fouled up the cat?
