i'm going to plug it but i still want to know what its for.

 

im guessing its for a wideband

 

if you have a evo 9 there is no use for the B pipe bung...
8's have a rear o2 sensor...so thats what its for

 

is for wideband sensor later on

 

I thought the cat back did have a bung for the 8?

 

 

oh ok.....yeah i have a 9! i would not be able to put a wideband in there right

 

 

Fail...

 

Oh God here we go again with this same person posting inane questions.

 

had to quote these....lol perfect.

 

I HAVE AN 8, NO A 9, NO AN 8....... NO A 9. YES DEF A 9..... I THINK. lol
