I was trying to search and will continue. Anyone have a picture comparison of the two? I want to know the angle output difference. Thanks!

I don't have a pic of the 2, but I can tell you that the evo3 o2 mounted aims more towards the passenger side where as the stock ones aim pretty much straight down.

I ported the shit out of a 2g o2 housing back in the day and it still was a bit smaller than the evo3 o2 housing. And like dude said above, evo3 o2 housing points at a slightly different angle, some 3in DP's ( like mines) get pressed against the tcase due to the angle. I had to smash my flex section in w/ my sledge hammer so it wouldnt touch anymore because the vibrations were giving me phantom knock. I dont run a evo3 o2 anymore though. Thats about all I can help...
