hey guys, need help with an install for OBX headers on a V6 - Hyundai Performance Forums

I posted already on the newbie section but I wasn't sure if anyone could help me. I purchased the OBX headers to put in my 04 V6 but i found them needing bungs so i had them welded in. I also found they needed cat, unless I wanted a CEL because currently no one makes an 02 simulator for my car. I recieved the HFC today and i'm wondering if anyone knows if they can be welded in there bc they don't look like they would fit. Has anyone successfully installed the headers in a V6 and how did you specfically do it? Where did you weld in the cats and what company makes them? I'm trying to do all possible to avoid a CEL so any good advice would be greatly appreciated.

You should be able to install them without the cats on the headers with causing an CELs. You will need to move the last O2 sensor down past the cat that is under the car, then you'll be okay.

So, the headers will be fine without a cat but I can weld in a HFC into the downpipe?These headers came with the aftermarket downpipe so that cat in the back under the car will be eliminated once I go ahead and take the entire thing out. That's the only way i see it happening. Anyway I can contact you thru messenger or something if I have any other specific questions?
thanks,
