Quick questions about kooks/obx headers

I'm about pick up some obx headers. Not sure if I want the cat or catless ones. My friend showed me kooks headers for only $200 more but they don't come with a y pipe. I don't want to spend more then I have to since I'm building this car on a strict budget. Is it worth spending the money on kooks headers without the y pipe or should I just pick up the obx headers. Can I use the stock y pipe or a pacesetter y pipe with the kooks? Yes, im aware of the history if obx but I've had them on several cars and they're great! My truck will just be sprayed, bolted and diablo tuned. Not doing anything crazy.

I'm pretty sure only kooks y-pipe will work with there headers. Personally bro, there are a shit load of guys on here running OBX headers with no problems. Just remember you get what you pay for.

My pacesetters were coated by these guys.... www.nitroplate.com

Pacesetter headers- 260 shipped from maryland speed to nitroplate
Nitroplate super bright finish- 250 + shipping from Nitroplate to you
Y pipe-150 shipped from maryland speed to you

Still cheaper than just the Kooks headers alone but you have the exact same product. The nice thing about the Kooks are the way they mount to their y pipe. With the coated headers and y pipe from pacesetter, you're still $600 cheaper than Kooks.... My Pacesetter headers fit great and have zero clearance issues.

I just bought some pacesetter headers and a y pipe. The kooks don't fit the awd apparently.:confused:

I was considering going this route, I just wish Pacesetter offered a catted y-pipe!

There have been a few guys that have added cats to it. Not sure but I *think* papabear might have added cats. The pacestter y pipe is pretty versatile. A lot of guys modify them for true duals and I know of one that cut the flange off and welded a 3 1/2" flange and full 3 1/2" exhaust. I'll probably be going true dual soon and I think that would make it pretty easy to add cats then.

Thats sounds like a cheaper option than SW or kooks.

A couple things. None of the other companies Y pipes will bolt up to the Kooks headers flange.

OBX does not offer cats to my knowledge and neither does Pacesetter.

Coated Pacesetters are the budget header of choice IMO.

I have seen the OBX headers WITH catted Y-pipe for ~$700. I don't think you can beat that for an emission legal setup.

How would that setup sound with stock cat back with muffler and resonator still intact? Think it would be any louder than stock?

Any better deals out there?

You sure those were cats and not just resonators?

Emissions legal isn't exactly correct. Hi flow cats are not emissions legal in any state. They just cut down some of the smell and may get you past a visual in some states. They will only pass the sniffer in states that require that on a very close to stock vehicle.


It would be louder then stock if you chose to go that route though.

In Texas it would be legal. As long as the vehicle has cats and isn't throwing a MIL it will pass.

From what I hear there aren't very big gains with headers unless you get the catless y-pipe. I'd like to see dyno info that shows otherwise though cause I'm looking for my next project.

I wonder if there are any dyno's out there showing the results. I know I picked up quite a bit on my 2002 Z28 with Hooker LT's without cats. And I had always read that the hi flow cats didn't hinder that performance much at all. I don't have any proff of that though.

Long tube headers on the F-Body LS1 setup is huge since the stock setup is so restrictive.

The cats are not restrictive like people think. If you're worried about a few horsepower or building a 1000hp monster then by all means go catless.

Didn't know they offered a cat now, but not surprising since I have never been in the market for a set.


In Texas it may or may not pass depending on the county you live in. The more populated counties (Houston included) in Texas have emissions that test the actual output of the pipes not just an OBD 2 MIL test. Similar to CA but with less stringent standards to pass.

Regardless legal would not be the correct word to use since it is against federal law to remove or change the location of the factory cats on vehicles so equipped. :biggrin2: In other words, headers with hi flow cats are just as illegal as headers with off road pipes. This is the reason companies make shorty headers that don't change the location of the factory cat so they remain legal under federal law. They aren't worth much power though.
