hi,

so I have kpro, stock header, testpipe, aem uego

I read on a old thread I am able to use the primary o2 and route it to the test pipe and stick the wideband into the header. can I get someone to confirm this? emissions ok?

I'm trying to avoid having someone weld another bung on. thanks in advance

 

I dont understand why you would have to weld another bung on?

Or are you just absolutely not okay with having the wideband anywhere but the header?
