Did you guys just replace the stock o2 with a wideband or did you weld a seperate bunge cause i know it mentions to have it atleast 10 inches away from the turbine because it cant get too hot. so what did some of you guys do? are there downpipe vendors that sell you a down pipe with a pre made bunge for an additional o2 sensor (wideband).

 

i have a full turbo back exhaust and i had a bung on my testpipe and catback so i just used the extra one for my wideband...

 

so you put it in a bunge on your test pipe? anybody seen any DP that come with a bunge at the bottom of it?

 

A lot of test pipes come with a bung already installed. I know for sure the MR one does.

 

I had a bung weld into my HFC, in the piping right before the cat.

 

Im gonna have to get a third one welded into mine. cause my rear is into a mechanical CEL delete J BUNG

 

you have to keep your stock O2 hooked up or you'll get a check engine light. you'll need to weld on a bung any where on the down pipe, test pipe or in front of a high flow cat.

 

Yea I knew that. But some can eliminate theier rear with an O2 sim and use that bung for the wideband

 

^^True but the closer to the turbo you get the more accurate the reading is going to be. If you have a cat you're reading will be off.

I ordered my DP from Buschur and had them weld in a bung for the o2 I had a BR dp before this and the local stop destroyed it trying to put in a bung (incompetent welder) making a 10 dollar job a 200 dollar job.

 

i have the dc catless down pipe. I went to a local shop and paid 20$ for him to weld my bung.

 

they have to cut the proper size hole out first right? can they do it without you taking the DP off?

 

My test pipe came with an extra bung.

 

Is it ok to put this in the testpipe?
