I have a 2005 Tiburon GT 2.7l V6 I have recently installed a complete stainless steel exhaust from DNA Motoring. I installed the whole exhaust system from the long tube headers all the way to the tailpipes, I also removed all 3 catalytic converters. I've heard of the o2 sensor bypass trick but I was just wonder if I am supposed to install the o2 spacers only on the downstream port or both, upstream and downstream?

The o2 spacers are only for the downstream sensors. The upstream sensors.must stay in the direct flow of exhaust gasses or you will have trouble with your AFRs.

That's what I thought. Just making sure before I go through with it
