Downpipe/O2 location

[Tom Walker]

I'm getting ready to install my new RJC 3" DP and would like to know the optimal position for a WB O2 senser. So, about how far down and in what position? Thanks in advance....

I've always put my wb02s past the dp at the start of my eghaust just past the firewall. Don't think there would be any issues on the dp just not to close to the turbo .

i put mine about 18 inches from the turbo, right by the firewall/ ac box. It's on the top of the DP so moisture doesn't collect in the sensor
