2011 Wideband install

[rmurer]

the instructions that came with my AF ratio gauge are pretty piss poor.

do the 2011 gt's need a bung welded on?

if you have a aftermarket gauge like a AEM then YES you will need 1 welded into your exhaust unless you have the rear o2 sensors disabled, in that situation just put the wideband o2 into on of the rear sensor spots.
