Stage 2 With High-Flow Cats?
Anyone here running a canned stage 2 tune with aftermarket downpipes and either 100 or 200 cell high-flow cats?

I am looking into this now, probably going to go with Mike's customs DPs with GESI UHO 300cel cats. Will upgrade to stage 2 with OE. I've been thinking about this for a while I just need to get on board with the cost. Curious as to what kind of info you're looking for?

I am looking at getting the FI downpipes with probably the 100 cell cats (along with the FI valved exhaust). Based upon what I have read, there should not be much of a back pressure difference between the 100 cell cats and catless. That said, I would like feedback from anyone here who has gone with a high flow cat setup on a stage 2 tune.

Very cool. Does the car seem to be running well? Did you notice much of a difference above stage 1?
