I recently bought a used LSJ downpipe and i have two o2 sensors. Is there a specific bung that i will need to be welded in? And how many people have CEL's after swapping the LSJ in? All input is greatly appreciated

 

lots of threads on the swap

 

bung is standard o2 sensor, ive had an lsj exhaust mani and dp on for a couple of months now and no cel's.

 

Cool thanks guys!
