Part number for the Stage 8 Header bolts you used. Thanks.

 

I know this is an old thread, but. so is anyone running the OBX LT's with the OBX h/f cats? Just wondering how well the cats hold up? Thinking about doing the LT's with the Y pipe to the Magnaflow SI/DO that I already have on the truck. I'm not looking for massive HP for drag racing, truck is a daily driver 4x4.
Is the o2 sensor haness' long enuff or do they have to be extended? Is there any issues with throwing codes? I have to pass Texas emissions testing.

 

I thought all this was covered in this thread. ? My cats are fine so far, I needed extenders and I threw no codes.

 

The hf cats I was referring to are OBX that they sell with their LT header kits. Where can you buy the o2 harness extensions?
Sorry for the question's, I must have missed a few things in the many pages I have read thru from the search I did on here for the OBX headers.

 

many people / shops offer the extenders...

 

Hey efuehrin great job with the post made me decide to go with the OBX LT headers. I'm gonna cut out the resonators and add the cats like you did. I know the cats are 13" long but my question is how long are the resonators?

 

^^^^I really have no idea. I'm not sure I even have them anymore.

Sorry man.

 

I found one of mine laying around. Roughly 7"

 

Thank you hockeyfan big help

No problem, add an inch for each bung hole (try to read that without laughing.. i can't do it even just typing it) so roughly 9" bung to bung.
