Help Needed Now

I just ordered a gibson exhaust system for my 3.4L tacoma, when examining under the car, i found that there was an Oxygen sensor after the converter. Does the gibson exhaust have a port for the oxygen sensor? and what do i do if it dosnt? Also how does it sound? whats the power difference?

I need a response now, so if i have to send it back i can before they ship it. Thanks

A bung can easily be added by any exhaust shop so no worries.
Didn't like the Borla?
