I would go with the best quality you can afford if you plan on keeping it for many years. pacesetters are ok, but if you can spend a little more, Headman makes a nice Tri Y setup.....4 into 2 into 1. you have to custom make your Y pipe to keep the OEM cats. the best thing you can do, is to use some smaller high flow cats. From what I have read, the OBX header might need to be slightly adjusted for a good fit but I have found even the $1k headers might a little tap here and there for clearance.

What ia your budget and overall goal. I went with stainless steel works long tube with cats...not cheap but the quality is spot on and I also needed high flow catts to keep the noise level down.

Good luck!

I went with the OBX headers with cats...still working on the rest of the exhaust. It's still stock for now.

The OBX where quite easy to install. I did have to trim the crossover pipe by about an inch. But that was a quick and easy fix. That was the only issue I had at all with the headers.

Those headers are the same as LPP, Pacesetter, Texas Speed, etc.. No you cannot run oem cats on them, you will need some small high flow cats welded in or just have the CEL turned off via a tune.
So yes they will trigger a Rear O2 failure code, which will do Nothing to your drive ability, merely a stupid light on the dash.
Thats what 99% of everyone does.

They will bolt up directly to your oem catback or any aftermarket catback designed to bolt up to OEM manifold/Y-pipe exhaust.
