anyone with a 2015 Silverado LTZ 5.3L

where did you have the wideband exhaust bung installed?

Permanent install...I am thinking somewhere near an oem o2 sensor in a downpipe from exhaust manifolds???

Any pics would be great..as long as YOUR install resulted in good wideband readings

thanks

I haven't seen my son's truck yet, flying to Florida and need to have this done tomorrow morning...lol

 

Right near the factory narrowbands before the cats is a good spot.

 

I read some are installing the Wideband in existing bung, AFTER cat with acceptable result.
Is there any reason NOT to do this ?

 

After the cat is not an acceptable spot. It's a terrible spot really. The cat will prevent the sensor from telling you the true readings. Before the cat is the only acceptable location.

 

DONE...before cat, driver's side down pipe, near oem o2 sensor

thanks guys
