Well, I dunno since I've never dealt with high flow converters, but tampering with any (working) portion of the emissions system is illegal, FWIW, and will likely throw any warranty related to any failure or running problem from removal of the cats.

Like I said, I'm unfamiliar with the function of high flow cats and how (if at all) they'd affect the downstream O2s.

Yeah so I'm screwed with getting new cats until my warranty is up!
