I was wondering if i were to install a hotshot header would I have to relocate one of the O2 sensor behind the cat. I read somewhere that my car has a pre-cat and a secondary cat and installing the header would eliminate the pre-cat. Anyone have any experience with installing this header?

well, yeah. someone will have to weld 2 O2 bungs in after the cat, and you'll need plugs for the 2 in the header. there will be 2 more O2 sensors that stay in the header.
I just got my header installed but ptuning didn't send me the fittings for the sensors that need to be welded on the cat. I'm driving around with the check engine light for a week, until i can get in and see the guy to do the welding work. My mechanic called hotshot to get the parts. Hopefully they won't make a big deal out of it and send me the parts. Would me not having the sensors hooked up ruin anything?

yeah you'll have to relocate 2 of them behind the main cat, in order to not have a check engine light.
man mike, you're telling him alll about the hotshot, yet you tell me dont bother lol
although im following your lead and having headwork/valvetrain work done. btw i talked to a machine shop. they quoted me around $600 for a custom made header, assuming i made and brought them all materials and all cardboard templates, and basically a cardboard&duct tape model of what it needed to look like. my only worry is that this is a machine shop, not a car shop, and they arent gonna worry about flow characteristics as much as i do D:
