hey guys, I've had my zzp catless for a while now...I ordered it with the angled bung to reduce the cel codes but I've gotten em pretty much since I've had it on...I finally replaced the rear sensor and it went away for like a wk and now throwing codes again...my question: is the o2 bung supposed to be on the bottom or side? my comes out of the bottom with the way it lines up and its always full of water or condensation....most pictures I've seen show the bung coming out of the side I think...any help would be great..thanks..i'm hp tuned also before you say turn it off with hp but its about a 3 hr drive

 

Yea condensation will kill O2s, should be mounted horizontal or at a greater angle and not in a sump area.
