im about to install 2 new o2 bungs on my downpipe and was wondering where would be the best place to mount them, such ***
right near the firewall or near the beginning of the downpipe
and should i put the o2 sensor before or after the wideband sensor
and if they should be spaced apart within a certain distance

would the readings be any different or better?

this is going on a 2.5"dp for a turbo sohc

thanks, tony...
