you're right, there's no sensor on the oem dp itself.Originally posted by frisco-wrx-dude
The sensor that u guys are putting this resistor is the one on the uppie am I correct? Cuz I don't see any sensor on the downpipe...
the rear o2s is on the mid pipe, which is downstream of the dp. some dps, however, replace both the oem dp and oem midpipe sections, which then puts the rear o2s on the dp.
i do believe that we're talking about the fix for a rear cat code, not an egt code, which is traditionally associated with the up pipe and it's cat removal. confusing, i know.
