My thought was pairing this with a JB4. I'd love to see real world performance gains with the package and what people saw with just one or the other on (that and does it pose any emissions issues).
Yes for the MOST gains, you want to go catless... but from what you are explaining you want (gains and not having code/emission issues), the HFC DP is the way to go. That's what I got and can't wait for my car to get here to put it on!
