Ok i told you all i was going to do a write up on how to change a header but i ran into 2 problems, nothing big.

1. to short of distance to the cat (no biggie take it to my muffler guy on monday)
2. What the hell do i do with this O2 sensor, on this pic my stock header has it, but on my 2nd picture there is none, what do i do with the sensor?





I tried to just have it disconnected but i end up with a C.E.L. anyhelp would be greatly appreciated.

Edit: Fucked up with the pics.

 

2. obviously u need the o2 sensor plugged so u wont have any CEL's...
are u saying u have no bung anywhere on your header??

 

Well that looks like the DC 4-1 to me. I have the same header and I had to have the muffler shop make a hole in the header just before the dump to screw it into.

 

well you can either weld in a bung to the cat or the DC header itself.. good luck

 

Well since your are taking your car in to the muffler shop for a short extension from the collector to cat, jus have the same person make a bung hole for your o2 sensor. Get everything done in one day

Nope no "bung", if a bung you mean the hole for the sensor. What i think im going to do is have my muffler shop guy, cut off the one from my stock header and connect it to my cat, between the flange and the cat. itself, would that work?

 

go buy the nut that fits an O2 and have the shop cut the hole and weld it on
