I recently purchased a Fujitsutubo Downpipe.. On inspection of the pipe I noticed no bungs for O2 sensors.. Do the sensors mount lower on the exhaust or will I need to drill and weld bungs on to the dp?

Any help would be greatly appreciated..

Thanks

 

there are no 02 sensors on the downpipe. you have one in the catback and one in the turbo elbow that connects the turbine to the downpipe.

 

Thanks so much..
