I'm getting towards the end of my G35 engine build/APS install and I need to have a bung welded on my APS dual exhaust for my wideband. What would be the best way to do this? Obviously, I"m going to be downstream from the turbo, and I don't have cats (shhh, don't tell) so I was thinking of going right in to my test pipe. Will I have issues if I'm only sampling one side of the motor? Should I look into having an H pipe made?

Thanks!

 

Just pick one side and put it on the test pipe.

 

I have the Wideband O2 Sensor on the drivers side and the EGT on the passengers side. Just worked out that way, no real reason.
