Kooks Headers......good and bad? I'm looking into buying a set of Kooks 1 7/8 SS headers and I would like to know what everyones experience is with them. There is very little actual information on this board. I have SLP headers presently and I'm not happy with how low they sit under the car. I had to weld a skid pad on the bottom of the collectors. Thank you!

Seems like there are fads on LS1 headers. I remember a time when Grots where the top dog. Then I hear a bunch of good stuff on TTS, then FLP, then JetHot's redesign of the Hooker header, then QTP and now the Grot-knockoff Kooks headers.
The reality is that every header manufacturer (or reseller) has a list of unhappy customers and a long list of very satisified customers. All of our cars are just a little different from the factory and it doesn't take much to make our headers a PITA to put in or to keep from banging something.
OTOH, SLP longtube headers have never been on the top of anyone's list who has been around the LS1 community or installed them on at least 1 f-car.
I'd say dump the SLPs and get whatever header is the cheapest from the ones listed above.

I agree with you Jason. Since I'm in the process of putting my 427 together I thought I might as well make the "step up" to a better header. I like the 1 7/8 size and the welds look top notch. I read somewhere heat is a issue with the SS. Is this a correct statement? Thanks.

I love my Kooks. The only issue I, and many others have, is the damn off road y banging on the floor board. Some 1" heater hose took care of that.
As far as the heat thing goes. Coating headers serves two purposes.
1. To keep exhaust temps higher, giving the gasses a higher velocity, thus allowing them to escape more quickly.
2. To keep cheap mild steel headers from rusting.
The first purpose is the most important, but as many have said before, the difference in HP gains between the various headers out there ranging from mild steel, to coated, to stainless are negligible.

So I too am about to get Kooky, and I have a couple more Q's...
How easy are they to install on a TA...do they fit, or do they need to be made to fit with a little bending and tweaking?
With the whole heat issue, would coated be better than stainless?
Are you going to get banging with the Catted Y pipe....
Most imporantly what else do I need....O2 sensors, exenders?
And who has them for the best price....i want them!!
Sank you!

Kooks aren't just a fad, nor are QTP. If you want top notch, high quality parts, for headers thats where its at. SS headers last forever, and the workmanship on my Kooks headers are great. No doubt they'll last me through whatever, til whenever. Well worth the money if you're lookin for no worries, great fitment and outstanding quality.

I've installed QTP and they are no better then a half dozen other header brands. They are somewhat unique because they are offered in stainless. OTOH, some would argue that stainless is a poor choice over coated mild steel. In any event.... get which ones you like. They'll all get the job done.

Even the SLP LT's are great quality they just hang too low and are a bitch to install and they are stainless & coated, you can never go wrong with stainless. SLP LT's make good power through the low and mid range power band some other LT's will make a little more up top. My next set though will be QTP's or Kook's.

Is there any information about hp gains with Kooks headers? It would be interesting to see. All I know is SLP's drag on the track and bumps in the road. I had to raise my car 1 inch for clearance reasons. Which is crazy!

Most headers will result in Y pipe banging, and a catted Y will likely be worse because cats take up more space. Some people will tell you to put heater hose on it or even weld a spring between the pipe and floorboard, but this doesn't fix the problem, only hides the effects. The only real way to stop Y pipe banging is to install poly motor mounts (at least on the driver's side) because they greatly reduce movement of the motor. I highly recommend that you do the motor mounts during the header install with no manifolds/headers in the way, as it makes it slightly less of a PITA.
