IMO if it makes a couple ponies over stock & has the integrated o2 bungs, that's a huge slam dunk! Perfect solution to anyone with Euro or aftermarket headers that wants to retain OBDII compliance. I know the integrated o2 is no problem (they offer it on their E46 section 1), so we'll see about power.
Also for those who don't want cats in their section 1, I could see this being a solid option as well while keeping noise volume down. I imagine headers + CPI section resonated + x-pipe + axleback would sound great, without rasp.
Let us know how it goes, Jack's a great guy!
