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.

You really are just a lonely old man that has to have an opinion on everything aren't you. I'm going to start calling you Ken from now on.   So headers only net you 15hp for $1500, and?

Definitely the word Ken   Still nobody cares...

Couldn't be more relevant. Those lower numbers are also at WOT. To get that 'additional' power you actually have to ask for it with the loud pedal. If it made power based only on rpm then you could no

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.

      Tire psi

      By jgaudet99 · Posted

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
