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.

I will kep everyone posted as the R&D goes on.

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...
Forum guys whine a lot.
We love pics.
Forum guys complain.
We really like sound clips.
Forum guys always know someone who will do it better for cheaper.
We like dyno numbers.
Forum guys ask a lot of questions... over and over and over...

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!

The headers are on the car everything is tucked up above the oil pan and the car run's and sound's great.

Is the only change the headers?

Your comparison between stock and now?

we need answers

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.
