Generation III External Engine - o2 extenders

About to order some and need to know what length will I need.....

12" or 36" BBK headers on a 2000 Z28

Thanks

dammit.... I have my rear o2s deleted. So do I even need to install o2s in the bungs on the headers???

nevermind..... read the install instructions on bbk's site. Getting the 12"

later

You have two set of o2 the fronts set is what you will use unless you have a sd tune the rears are just fod the cats

Thanks Astro... had a brain fart.

Def going with the 12" bbk extenders...... I ordered the headers and some 13111 o2s, but the o2s will not get here until Monday (7th) :mad::mad: Said F it and ordered the extenders from amazon using my prime to get next day shipping for a paltry $3.99!!!! Figure I can use the Bosch sensors when/if the stockers crap out.

Thanks Again

You have to have extenders even though you have the rears tuned out?

I think the front o2s are moved back about 8 inches from the stock location.....

My 02s are tuned out unplugged and taped up but i have a ory with no rear o2 bungs

i think you read that wrong. theyre not 3.99, theyre 39.99 shipped. right?

Shipping is 3.99 next day Extenders were 39.99 or a tad more

Using Amazon Prime for a free month rules with shipping

My rears are also turned off and I will reuse the plugs in my stock y pipe to plug up the rear bungs on the bbk y pipe.
