Yes it will provided he dosen't go the shorty route like I did. If he goes with the shorty then he'll have to get a u-bend delete as well. All an exhaust shop will do is use a scrap piece of pipe and either cut a hole for the o2 sensor or weld a 02 bung to the pipe. The guy used a plasma torch and cut the area around my o2 sensor on my ubend then welded it into the delete pipe. It didnt mess my sensor up due to him cutting away from the sensor.
