I talked to Chris over at Kooks and he gave me some optomisitic news that I thought I'd pass along... as apparently the V2 system will be a priority. Maybe some of you already knew this but it was good news to me.

"As soon as we get the CTS-V here, which should be very soon we hope. We will have an entire system made up for it. Kook Jr, the president of the company is actually planning on getting one of these :)"

Agree. I'd purchase in a heartbeat if it improved performance AND had essentially NO ISSUES. I do NOT want to be tightening header bolts every other week or not pass smog, or, etc.

Any word on if American Racing is going to be making these headers?

From what I have seen in the Corvette world, American Racing makes better headers than Kooks for less. One of the guys that used to work for Kooks left and started American Racing.

I wonder if they'll be able to gain substantially more than the 6whp that WAIT4ME performance experienced with headers (http://www.cadillacforums.com/forums/cadillac-cts-v-series-forum-2009/158463-potential-mods-power-gains.html).

I don't know if I'd want headers on a V2. Might be too abrasive for the high-class bad-ass image...

I'm sure their marketing dept will show substatial hp gains. I'm also betting price will be $2500 or better.

he said around corVette pricing so i'd expect $1,500ish for the headers

At those prices, there'd better not be ANY fitment issues--zero, zilch, none.

since I have kooks on one of my vettes and american racing on the other.....and do all of my own work (yes including dropping motors) and have dealt with both companies face to face...

Go with American Racing. I've personally installed 1 7/8ths with no cats in my 99 vette (road racer) with a 427 C5R, and 1 3/4 with cats on a friend's 08 when I put a blower on it this past fall. Both sets went in like they belonged. The kooks in my 00 vette (drag car) are 1 7/8ths and honestly....I need to drop the motor to have them fit, they need the starter out, alternator out, motor unbolted and jacked within the cradle etc. The fit and finish goes to american racing as well. Buddies of mine also did back to back tests of these two header systems on an 06 Z06 when they first came out along with LG's and the American Racing went in the easiest and made teh most power. They're dealers for all 3 but wanted to get a realistic idea of what to spend the time with.

Since we're dealing with pretty much a vette motor (minus a few changes) I'd go with whats worked best for the vette communities personally.

I know when I pick up a V thats who I'm calling, hell I might even stop by on the way home from the dealer if the box will fit in the trunk. :histeric:

Just thought Id update you guys, I dropped my V2 off at Kooks on Saturday and they will be using my car for prototyping and begin fabbing the headers up as soon as they finish a current project they are working on, so it wont be much longer :)

its a good time for them, too early before racing season and they were the ones that picked this time, so they will have it for a few weeks to do the fabbing! nothing lost on my account, the weather, minus today has been inhospitable for the car.

I'd LOVE to see a tuned V dyno sheet immediately before adding headers, then re-tune the V after the headers have been installed and see what it does. I think that would add a lot of value.

Undertaker thanks for all the kind words. I am wondering who is this friend you speak of that we held up? As for your experience with our company you are comparing a header that we designed almost 7 years ago. Is it a little tricky to install ? I guess it depeands on who is doing the install. We do C5 installs here in under 5 hours. We do multiple install's here a week our C6 install time is under 3 hrs from start to finish.

But lets get back on topic here like the title says KOOKS HEADER SYSTEM FOR THE 2009 CTS-V. We have the car disasembeled right now.There are so many design flows in the factory system it is really crazy.I am going to post up some pics of the factory exhaust system so the forum members can see what I am talking about.

The Cat back is where the gain will be. Fully removed it was 18hp gain... Headers wont be much if any when you put the stock catback back on.

Thanks for posting up George! We look forward to your impressions and development of the exhaust.

A couple of important things to remember...

We love pics.

We really like sound clips.
Forum guys always know someone who will do it better for cheaper.
We like dyno numbers.

I had a set of kooks LT headers for my chrysler 300C SRT8, i LOVED the sound when combined with the corsa catbacks, i LOVED the performance as well. Only problem I had however, was the clearance over speed bumps. The headers were hanging too low and I had to crawl like a snail over speed bumps so that they wouldn't scrape the headers. It wasn't the case though with my friends Z06. I just hope they design it with clearance in mind as it seriously affects the cars driveability; it was the 2nd biggest hit on driveability other than the cams i put on lol. (btw i removed both cuz the cops don't like me :()

Ditto. Have Kooks LT headers w Hi Flo cats on my 300C (non srt8)..plus cam, heads, tune etc. When combined with the Corsas on there--the sweetest exhaust note I ever heard--and I get told that often. But same problems--they hang low and scrape on large bumps or speed bumps.

I heard that! No...seriously. Almost every speed bump my Kooks scrape. Glad it's not just my car.

The check engine light problem with a higher flow exhaust is a tuning problem not an exhaust system. Any better system should flow exhaust faster and if it does it will suck fuel out of the engine that needs to be replaced with tuning otherwise you get a lean condition which will trigger the light. Happened on the Lightnings all the time until one's tuner added some more fuel.

As for the Kooks headers, I ran them on the Lightning. They were good and held up well except I bought the coated version and that pitted bad and no one would warrant them. I should have bought the stainless version. If they offer both coated and stainless buy the stainless. Other than that they were kickass!

Sorry for the delay of information. We have made some changes to are original design. The first set of headers we produced where not up to our standards. meaning we do not want to have to oval or crush any area of the pipe this is a luxury automobile not a F body. So we are making a complete design change to the header so not to sacrifice any ground Clarence with the new design. And it will not require any crushing or ovaling of the exhaust pipe.We are also going to offer the system two ways.
1st option will be a complete system from the headers to x pipe catted or off road to our Kooks axle back Muffler system. The catted system utilizes our own high flow catalyst which are rated at 400 cells per inch not the 200 that most other manufacture are using. We use this cat on all our catted system. To reduce the smell of carbon monoxide out of the system. We have also found in emission states that run the sniffer it is much easier to pass without a tune.Each cat flows 572 CFM.
2nd will be a full system that you yourself can retain the factory muffler back with a simple modification of cutting the factory exhaust and add a band clamp to seal the system to the our x pipe..
I will post some pics here next week as for the headers are on our Laser vector machine so we can create a cad design for our bending department. Once that is done we can go into production with the headers. Should be done in the next week or so.

Good afternoon Ladies and Gentleman. First let me say I am sorry for the delay. With the move going on it really has been occupying allot of our time so I have not been very active on the forums. I apologize for that.

Now for the good stuff the 2009 CTS-V system is done completely now. I will enclose some pics of the system in this post but first lets start with the details about the system. The headers are made of 304 stainless steel from start to finish. They are tig welded in the entire section of the flanges then hand ported so there is not any obstruction of flow when the exhaust gases leave the exhaust port. We use one of our 6 mandrel bending machine in house to create the perfect wrinkle free mandrel bends that make up the primaries. Then the primaries enter our Venture spiked stamped merge collector. Then the collector ends with a ball and socket design for a leak free connection. Then the exhaust gases pass through our all 304 S/S x pipe that is sectioned using our Tas 300 S/S clamps.Making the system made from 304 S/S including the clamps. Now this is were you have options. We make a x pipe system that will connect to the corsa exhaust if it is already installed on the car. Then we offer a factory connection point x pipe. Then we also offer our own axle back exhaust system. Witch exits to an oval tip that complements the rear fascia of the car very nicely. Here are the part and pricing break down for each of the Assemblies listed above.Bitmap GM Motor Corp.Page 13GM / CADILLAC CTSVLS9 (2009)Headers are made of Stainless with 02 Extension Harness and 3" Stainless Steel X-Pipes (Catted or Off Road) for OEM or Corsa Exhaust.Item IDOrder HeadersGasket

To George@Kooks (or anyone with Kooks installed): the drivers-side cat on the Kooks system appears to be mounted right where clearances are really tight on that side; does the cat end up protruding below the unibody "rail" or the trans pan at that point? Thanks in advance...

Blah, blah, blah...Kooks are a great product. All American as any, Family owned and operated. I have them on my 08 Z06 ad they are indeed sweet.

American Racing, also a great product, but not better by any standard. My Vette Tuner carries both and doesn't recommend one over the other.

That is a good combination if you are concerned about the car being too loud. Adding any aftermarket performance muffler will most definitely increase the sound decibel over the stock mufflers.

Does anyone have a preference of ARH or Kooks? ARH is a bit cheaper. Or is kooks including the mufflers too? KPE looks like a nice exhuast but their headers are full of welds:ill:, are expensive and only include the cats it looks like. I want to ask KPE if they can sell the Mufflers only and bolt them up to ARH. Now that may be a combo. Kinda liked the sound of those KPE mufflers. Pretty sure the video is with complete system. Not crazy about the Corsas. Borla got anything yet?

I have seen Kook's quoted with only the headers, headers and x-pipe, headers with x-pipe and extension tubes back to the factory muffs. I have seen discounted prices from $ 1800 (about 5 months back) to about $ 2100 depending upon who you are ordering from. I think that the prices are very similar. Kook's gets about $ 300 more for Jet-Hot processed headers. I am planning on going that route back to the factory muffs.

For the record, Behe and Luke were willing to do what it took to make me happy. But having to deal with Kooks was going to take time. And after 1 week for the normal work and then another week tacked on(the recoating took only a couple days, my schedule wouldn't allow me to pick up the car until the weekend), 2 weeks was long enough for something of non-essential value. It's an aesthetic thing that didn't mean enough to not get the car back.
