Exhaust system
 

:help:
I'm looking at different systems and due to the fact that my 91 supra has a cat converter and 2 oxygen sensors you cant take it off .... so now i have to buy a engine management system.... ? is that the only way?

Its called a "bung", weld it into the exhaust pipes for the 02 sensor to bolt up

But, while were in this subject
I know the bung is not gonna work with the mk3 o2 sensor since its on a flange with two bolts

Here's my question, if I used another 2-wire o2 sensor , will it work with my car?
Cuz idk where I can find a flange for mine
So I'm gonna try to use a 2-wire o2 sensor with the thread, so I can use a bung to weld on my downpipe

Bung, thats a funny word.

I need TP for my BUNG HOLE!! :rofl:

I guess there's not many choices .... guess well have to smoke da Bung!!

are we still on that Puff Puff pass rule?
