The_aSSet Posted November 20, 2012 Report Share Posted November 20, 2012 any info on the price? btw would'nt 2" primaries be kinda big for a stock lq9? Way too big. IMO but good for the big cubed guys Quote Link to comment Share on other sites More sharing options...
RevolutionRaceWorks Posted November 20, 2012 Report Share Posted November 20, 2012 Krambo the plan is to make them fit the awd trucks as well as the classic 2wd and possibly roll into a NNBS truck platform as well. I actually gotta fire him off an email now Quote Link to comment Share on other sites More sharing options...
zippy Posted November 20, 2012 Author Report Share Posted November 20, 2012 They are big for a stock cube truck, that is correct. A 2" primary header is basicly there for trucks that are 400+ inches or extreme 364's such as idahoBLKss's truck. If you had an LQ9 that is pushing 15psi of boost than a 2" primary would benefit you. For a stock motor mildly modified or with a low boost setup a 1 7/8" header is plenty. There are many 400+ cubic inch trucks out there now and it is great to at least have the option of a bigger header like the F-Body and Y-Body guys have. As I see it any time I can pick up more power by simply making the setup more efficient I'm all for it. I've dyno'd many vehicles with different size headers and there is certainly a gain in having the right size header for your setup.As for fitment, Kooks has assured us that they can make them with no fitment issue's and with the quality I've always experienced with Kooks I don't doubt them at all. It took so long for truck guys to even be able to get a 1 7/8" header that I'm really happy to see Kooks willing to step up to the plate to help me get a 2" header made. When you look at the power many on this site are making a big tube header will be nice to have as an option. Currently the track times list has 10 trucks running quicker than 11.8 and to do so in a truck as heavy as the SSS, that's some real power and moving some real air.

kissfans03ss Posted November 20, 2012 Report Share Posted November 20, 2012 So a truck with forced induction would be a candidate for these headers then? Sent from my DROID BIONIC using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

KrausMotorSports Posted November 20, 2012 Report Share Posted November 20, 2012 This is just a thought and only Kooks can answer maybe? Obvious looking into this new header deal but also would they help in the price department if I also order these along with the headers for my 12' camaro ss/rs ls3???

idahoBLKss Posted November 20, 2012 Report Share Posted November 20, 2012 on a side note out of curiosity how big is the exit port on the exhaust hole on the head ? at what point does it not make sense to upgrade to a bigger header if your not running ported or bigger heads ?

zippy Posted November 20, 2012 Author Report Share Posted November 20, 2012 I'm not even going to get into that discussion. This is a post looking for interest in those who want to go to the bigger header. You either have interest or you dont. If you're making more than 500RWHP you will see a gain in going to a header around this size. A stock 317 casting isn't even 1 5/8" across so by all means just put on a 1 5/8" inch primary header and you'll be just fine. Quote Link to comment Share on other sites More sharing options...
idahoBLKss Posted November 21, 2012 Report Share Posted November 21, 2012 I guess i should of been a lil more specific on my last post as it wasnt intended to start a bickering war about weather or not its better. I was trying to get at if i upgraded from my current lt's if it would be worth it or not before i got some better flowing heads that have been ported. But either way im interested but wont be able to do anything till after the new year anyway . Quote Link to comment Share on other sites More sharing options...
ric Posted November 21, 2012 Report Share Posted November 21, 2012 Way too big. IMO but good for the big cubed guys yea i figuerd, it'll be nice if they offered different sizes though instead of just them 2" Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted November 21, 2012 Report Share Posted November 21, 2012 yea i figuerd, it'll be nice if they offered different sizes though instead of just them 2" They have 1-3/4 and 1-7/8 Quote Link to comment Share on other sites More sharing options...
world class Posted November 21, 2012 Report Share Posted November 21, 2012 Hey Guys,I am Drew, I work at Kooks I spoke with Zippy @ SEMA a few weeks ago and we had discussed this header for the Trucks that can benefit from a bigger tube. This header will have to go through some prototyping and may take a little time to get finished. If you are willing to wait we can get it done. We do not believe the fixture that was built for the 1 3/4 & 1 7/8 will be able to build a 2 inch header on. If the interest gets us to build this header it will probably be fit up against my personal truck, as this was the way it happened last year for the prototyping update to the early GMT800 trucks. Our headers fit 1999-2013, with the corresponding Y-Pipe to the specific truck. To also answer the questions of other vehicles, and the existing headers for specials contact Revolution Race Works he will be able to get you pricing.Any header exhaust related questions i will be happy to answer.

zippy Posted November 21, 2012 Author Report Share Posted November 21, 2012 Kooks does make 1 3/4 and 1 7/8" headers that fit the SSS truck already as said already by the_aSSet. This post is about them working on them building another option which is a 2" header for the big power guys. I was going to post a link to their site, but I'll wait until their site is corrected. Either way if you want a 1 3/4 or 1 7/8" header and are interested in Kooks brand for your SSS or any 99-2012 Silverado they currently make them. I just checked their site and it does say 2009-11, but that will be corrected soon. I'll be sending pm's with pricing tomorrow, but anyone can call for pricing from here on.
