Anyone installed this? I'd like to go with the HFC version, assuming it can pass emissions and not throw codes, but my concern is on performance. The varied consensus on downpipes is catless is the way to go and even high flow cats are still cats and are not really 'bang for your buck' purchases.

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).
