i was just woundering what those of you who have a y7 did about the secondary o2 sensor when u got a header.....thanks...

 

^^^^^

 

on a y7, the cat is on the exhaust manifold.....

 

yeah sorry I was thinking of an SI or Ex.

 

^^^^^

 

im pretty sure dc headers come with a o2 extension u plug in to make it longer

then u just need a cat from any other honda

ic...can anyone comfirm?....and also if you buy a header and then cat back exhaust. that leaves no room for a cat....the header blots strait up to the cat back...

 

i hacked my o2 sensor wires and extended them..DO NOT hack your stock wire harness..worked fine for me..

extended them to where? how did u get a cat in there?

 

^^^

 

the y7 header has an extension pipe hooked up to it from the cat side of the stock header to the exhaust
remove that
add whatever u header u choose then add a honda cat
they both meet the exhaust at the same spot

if u still dont get it
lemme break it down 4 u

y7 header+extension pipe=y8/aftermarket sohc header+honda/aftermarket cat

 

so the y7 exhaust manifold+extention pipe is longer then that on a y8?

 

Same question here. The headers I bought already came with the sensor wire extended, and I unplugged the battery and the CEL still comes on. What to do? Im using the headers with the stock exhaust piping and muffler.

i thought i explained that they are the same length because the y8 header doesnt have or need an extension pipe because it has a cat

y8 header+cat=y7 header+extension pipe

 

ebay headers+apexi n1 cat back+extended o2 sensor wiring...no cat no extention pipe...all on y7..
