I have a 3 inch downpipe, it was mated to a ported stock O2 housing, worked fine. I swapped to an O2 housing that I bought second hand, its made for external dumping the internal wastegate, it came off a 2g and I was told it might be punishment racing. I put an EWG on this. Well its together and fits, but my downpipe is pretty tweaked now, its up against the transfer case, which I think is making phantom knock. I cant tell if its an evo O2H and maybe thats why? I know the evo housings put the DP at a different angle, and the bolt pattern is different, but HOW is it different? is that the angle it pushes your DP? Cause from what Ive read it doesnt look like an evo O2H will even bolt up or come close to working without the right DP, Mine bolted up okay just sits a little differently. Hard to see in the pic but the O2 sensor placement is a little different, it actually points towards the back, might not of even cleared but I just cut it off (im on sim O2)
