The kooks headers are now installed. The directions from kooks were completely BS. If I can give advice to anyone doing this in the future just drop the motor... DO NOT FOLLOW THEIR STEP BY STEP.

moving on. they sound great feel great. i already got a CEL, but, i have a dash hawk so no big deal.

I ordered and recieved the cat sims from hennessey today after the install...
I have never been ripped off this bad in my life. 2 metal adapters, $100 and they only do COD no credit cards. that company is BULLSH*T.

I will be installing the recently ordered cam in 2 weeks... damn these trucks are fast.

Where do the Hennessey sims go, at the pcm or rear o2 sensors? Do they require you to cut the wiring, or do they have plugs? Let us know if they work.

Kooks and Hennessey...two pathetic companies that will NEVER see my money. We'd all be better off if they fell off the planet.


Hennessey I agree but KOOKS? They make a great product for our cars its not there fault DCX's codes are so hard to break into to get rid of the CEL, get the headers then voice an opinion or ill let you drive mine and you will understand.

sorry bro but kooks is one of the best custome header companies there is.
yes believe it or not the sims do work... for now... after a 100miles no cel!
they screw into the o2 sensor wholes under the truck 3 min install... a rip off but with not other options its a must. mine w/ out the sims threw a cel with in 10 min of driving...

:confused: Look at all the problems you had Tony. From what I've read on the forums, Kooks is a company to stay away from. I thought you had nothing but problems with their headers?!

Tommy 25000 or Inferno, any drivability issues with KOOKS such as idle, noises from engine bay that were not there before the install etc... I almost purchased the KOOKs that HOTROD advertise for 1299 a few days ago but someone beat me to it. I have had headers installed on all the sport cars and trucks I have owned-20 I can think of. Headers make power.
thanks for your feedback

No man the problems I was having were due to a motor mount coming loose and the engine shifting which made the headers shift and kept loosening the header bolts up, I fixed the mount issue, ditched my half ass dealership (westbury) had KOOKS replace a header gasket due to the engine shift and all is well. KOOKS is a first class product, dont let the CEL issue sway you not to get them, once a good sim comes out or just use your dashhawk to clear the CEL. I can go up to 300 to 400 miles with no CEL.

Use the factory gaskets, even Kooks is recommending them over the felt ones supplied in the kit. I had a leak after 5,000 miles and the gaskets were burned through.

Looking on board for tips to direct mechanic on installation of Kooks headers. Not that he needs it, as he is owner of some nice show cars and a few strip cars, very experienced, lift in shop, etc. and he's installed turbos and downpipes on cars for me before, but still any tips would be helpful regarding our set up on this car.

So far, my search of the site yielded some photos of installed StainlessWorks, close up photos of the primary and secondary 02 sensor ports, B&B link to video of install of their catback exhaust system, opinion that the stock gaskets are better than the felt ones included by Kooks, that dropping the engine makes it easier (though that ain't happening here), and that the install requires every sort and shape of 10mm tool. Also note that it took most people a good day to complete. Tales of black smoke and safe mode triggering all seem to have been linked to alleged 02 sensor mixups (will be reminding him to label prior to removal). If anyone has posted a "step by step" or if there are some other noteworthy tips, like how not to break the 02 sensors on removal, special tool that might be helpful on one of the hard to access areas, if anyone has used a pair of stacked and modified sparkplug arrestors for their secondary O2 sensor ports, I'd be happy to see them.

Noob Questions Please?

Don't our stock Jeep SRT8's have casted factory headers?

Kooks are long tube headers correct?

What are the horsepower differences?

Thanks,

Please correct if I'm wrong, but nobody has popped a CEL with the Stainless Works headers. Only with Kooks, correct? From what I have read (I have NO hands-on experience, mind you) it is the location of the O2 sensors on the headers/catted pipes that is causing issues for the Kooks users.

The difference that I see is the cats are side to side on the SWorks on the Kooks there not side by side and the only CEL you get with Kooks is catalytic efficiency in bank 1, I may go to straight pipes, ive had it with catalytics.

They are exhaust manifolds by definition. They are not cast, there is 3 steel tubes surrounded by a steel covering-giiving them the appearance of a more tradtional looking exhaust manifold. The first 2 exhaust port tubes of each bank y into each other for a total of 3 tubes at the collector. I have been workin on these a while,there is a large 1/4 inch weld bead on the I.D. of all the tubes,restricting flow-The O.D. is now welded and all the inner welds removed-should help with flow(a little cheaper too-:D ) Here are some pictures of my gasket matched, ported & heat coated shorty manifolds.

That is what I've read here so far, and that that the "SIMS" are inserted in the secondary 02 sensor ports to adjust/trick what exhaust it reads. Just trying to get the benefit of others who have installed before me. WIll update.

i`m considering having headers installed. all said and done i reckon the cost will be somewhere around $3500-$4000 dollars. looking back,was it worth it? if they need to lift the engine and then put it back i wonder if everything will be the same like no rattles or any other unforseen thing that would piss me off that i did`nt think of and kick myself later for. i know this and that varies but what increase in horsepower do you think you gained.

After you take out the tranny support cross member to remove the front drive shaft and mid-pipes, re-install the brace. This will allow you to move the vehicle up and down on the lift as necessary. (lift is a must IMO). To remove the inner fender wells you will have to remove the plastic pop rivets. They are not reusable. You will need a special rivet gun for plastic pop rivets to install the new plastic rivets. Rivets are available at the stealership. Remove CAI for easier access to the top front passenger side header bolts. Small hands and arms are helpful because the top three bolts on the drivers side are a b*&ch. Have every 10mm tool ever designed in order to fit into all the different angles. These tips are from Hows2nd from the "other" site.

Those of you who have recently installed Kooks, did you use the supplied gaskets or different ones? Also, are they still throwing CEL's or has there been a fix?

An easy and very cheap rear 02 sims is taking 2 spark plug non-foulers, hollow out one and stack them, thread into the bung and then thread in the 02 sensor, pulls it out just right to keep from throwing a code cost is all of about 10.00 for all 4 needed. I have a buddy making these for those who do not know how or have time to hollow one out for around 30.00 for the complete set. I do have an extra set if someone wants to put them to the test and I mean they are ready to do it now just PM me your address and lets see if they work. Mopar has a Multi layer gasket with graphite that I would use and maybe some stage 8 locking bolts for the header bolts

Pretty sure I said 2 things that were constructive read the last sentence that I posted. Those are the only 2 ways possible to get rid of the CEL unless you jimmy rig something. If you dont find this constructive then I would simply say that you are the one that has issues.
