i just recieved my zzp 2.5 inch catless dp and i picked the option with the o2 bung for the wideband. but my dp only had one o2 bung should there only be one?

 

this is exactly what I was thinking about earlyer

 

Just goin out on a limb here, but yes i think you are only supposed to have 1. if it were catted i believe you would have 2.

 

bump.

 

Im turbod an i pickd the o2 bung an got 1 so u might be good,

 

thats normal with zzp they will only put one for catless only if you order an extra bung, with a catless downpipe, you wont need the rear o2 sensor as most people will disable that in their tune....

If you ordered a dp without the wideband o2 bung you wont have any bungs on ur dp...

 

catless would only have 1 in it.. cause u would have no need for a o2 sensor there...
so if you chose no bung and going catless you would have 0 holes.

 

Catless doesn't get a bung as there is no point for the rear o2.. So if you picked the wideband option, you should have 1 bung.

 

where is this bung?I have this down pipe too, and that bung placement is wrong for the wideband on mine its only the downstream one, The wideband needs to be the closest to the exhuast manifold for the best and most accurate reading.

where it should be

 

thats your answer if the bung is in the correct place^
