i have a 99 si b16a2, and gonna get hondata s200b with the p28 ecu. i will have a 3" downpipe connected to a piece of flexpipe then 3" pipe all the way back once i get everything on. i have two o2 sensors and i was wondering if i just put to bungs on my exhaust pipe and then get it tuned, will that be ok? ive seen that some people put one right after the discharge flange.

ive been reading alot on this o2 sensor thing but it sounds like most of the people that have had problems with it are the ones with the afc hack.

just wondering once i get the dp-flexpipe-exhaust on should i just put the o2 sensors where they normally go? do i need to worry about this open and closed loop thing if il be using hondata and not tuning it myself?

 

i should be ok just putting the o2 bungs where they usually are, right? i dont need a e cutout.
