I saw that Kooks is offering exhaust and headers for the 6.2 and 5.3 models.  Anyone planning on getting them?  I'd like to have the headers/y-pipe combo but it's still a little rich for my blood so far.  Hopefully prices will come down once they've been out a while.

Wow! $4k for a little sound and better flow just to be choked back down by cats. I'd rather spend that plus 2 more on a supercharger

I don’t disagree at all, kooks usually makes really good stuff. I know the corvette guys swear by them but at 3100 for just the headers....I’m gonna pass.

Kooks makes good stuff, but, Man! that's spendy!  Tempting, but I'll wait a while to see what others will be offering and some comments from actual customers; no feedback on their web site yet.  And thinking about getting down in there to reach the old headers and install the new ones doesn't fill me with excitement......  Man, they really buried the engine down in there, didn't they???

 

Best headers I ever had on a truck were Doug Thorley try-wyes, but that'll never fit on my new truck.  

 

I do wanna get me some headers.......:thumbs:

If your going to supercharge headers are a must.  I have stainless works on my supercharged 408 stroker in my 03 2500hd. Real nice quality headers that fit perfect, sad part is the expensive headers last and fit perfect.

 

Headers are good at all power levels with the flow, the smaller flow tubes help the torque range. A full exhaust with the headers is a must if u want the full potential.

prices went down starting at  $1,389.75.

I do have Kooks headers/cat-less down pipes on my Redeye, with stock muffler and really sounds great!

btw, Kooks products are very good in sound and finish.

at this moment NOT planning on installing headers on my Trail Boss, prefer muffler delete/CAI.

Headers are only good if you run your motor and high RPM.

Not true.  5.3's have consistently shown increases across the curve with headers.

Isn't it a good idea to do the exhaust when adding a supercharger?  You are cramming more air into the cylinders and expecting it to flow out the stock exhaust and not take a performance hit?

Yes you absolutely want more flow out when adding a supercharger, but if i went that route, I would eliminate the cats altogether to allow for more out flow. Doesn't matter now since I traded the truck in for a diesel

You can take stock manifolds pretty far in some cases. The CTSV and ZL1 camaro's will do alot more power than stock with factory manifolds. Even back in the day with the Cobra/Terminators, guys kept the stock manifolds because they still make good power.

 

Even most of the turbo LS's run stock manifolds or at least the drivers side is factory with a new cast turbo manifold on the passenger side.

Has anyone added the kooks headers with ultra green y-pipe and not tuned?  love to see the dyno results.

    • Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.
    • Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart? 
    • Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.
    • Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue. 
    • I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
