Tune yes ... cam no...  You ever even do headers on a 6 liter there Jim Bob lol.  The pickup with long tubes is pretty substantial with the stock cam.

 

But to answer well you have a few choices.  If you want to throw down like $1600 plus dollars you can buy some American Racing long tubes which personally I think are a waste of money.  They will however come with a connection tube that "should" bolt on.

 

On the other hand you have Speed Engineering and TSP that both offer headers for the 1/2 ton 6.2 trucks 07 and up and they fit in this 2011+ chassis.  I can't say if the 3.5" Y pipe will work without modification but for a T304 stainless long tube with 3/8" flanges and fit without modification for a 1/4 of the ARH..... I would take that and mod the Y pipe if need be.  

 

I run the 1 7/8" primary Speed Engineering long tubes on my other truck and they are a good bang for the buck.

Hey I checked out speed engineering website, the 1 7/8 headers for the camaro and firebird cost around 260, is that the same headers you got

I was planning on getting headers for my truck too.  Shorty BBK or JBA.  I have a canned tune and CA intake.  With the exhaust being stock, you think there will be any notice in low torque gain?

Honestly. My opinion. would be to not bother with shorty headers. Not enough gain, especially in the lower end torque department.  Shorty may gain you a small amount of top end hp. But not really anything down low. Long tubes will give you much larger gains across the rpm range.

Kinda the same thing I have found researching exhaust for the 6.0 on my rock buggy, unless you can fit long tubes just stick with the manifolds.

How much power is gained with headers over a stock tuned 6.0?

15 to 20 whp if you have a good catback already.....totally stock and moving up to something better catback wise could net 25 depending on the stock junk.  Pretty good gain for something that has a zero affect on the vehicles drivablilty.

Is that 15-20hp across the band or at peak rpm?

 

I have seen many dynos with cold air intakes that show 22hp gains yet they are down power everywhere but the specific small spot where there is a gain. Fakenews...

 

I am a header fan but a small cam L96 that doesn't spend much time in the 4000+rpm peak power rangers I just don't see making huge gains where they are needed.

The cam isn't that small for one thing and if you don't want to rev it.. well.. buy a diesel.  Using my own truck the bottom end was pretty substantial... went from a truck that couldn't squeak a tire to being able to light them with ease.  I didn't dyno it because I don't give a damn lol.  Truck was tuned prior so it's a pretty good comparison.  And that was 1 7/8" prmaries feeding 3" duals.   You need to actually to do some mods man... not just complain about your trucks.  The Ford you buy will be the same thing.. and Ford's are bullshit to buy parts for.. or tune... or anything.  I had 2 6.2 Fords trucks and went down that road to the point of heads and cams.

No use the truck headers.  Not the car stuff.

What do you want to do for exhaust behind them?  You can hook the stock forward O2s and wiring up into them as is.  

Basically yes, if I get the 02 sensor option I should be able to take my 02 sensors and put those on the headers and plug them in just like it was factory. now, do I need my cats as far as it throwing a code, if not id rather take them off, havent decided if im going with duals yet, ive heard people say ill lose low end torque but gain more on the top end, but pipe size (single vs dual)  will have alot to do with that also

      A/C failure cause???

      By Somethingclever_2014GM · Posted

      Glad it worked for you. I tried that 1st, about 2 years ago. Didn't help. I also tried doing a hard reset (disconnecting battery for minimum of 30 minutes). Worked a couple times, but after one summer of doing it over and over, that no longer worked.  I was fairly confident it was either the compressor or a failed actuator, but I just couldn't identify which one. Had to research which actuators do what and which last numbers are associated with each.

      Took me FIFTEEN MINUTES to find this. Isn't that a problem? On the mainstream media I can INSTANTLY find 100 articles bashing President Trump ... but when it comes to TRUTH in American corporate news & search engines, it's carefully filtered to support ONE SIDE. A Republic cannot survive like this! Incredible! Even all the AI searchers out there failed as well! ChatGPT said it needed more details on the video that I provided a DIRECT LINK to! I thought AI was the be-all, end-all?? I had to dig it up myself. This should be FRONT PAGE NEWS!!! 🤬   Here's the statement directly from our President:     Glenn Beck's reporting on the operation:   https://glennbeck.com/watch/videos/trump-just-revealed-a-massive-military-secret-that-lowered-gas-prices   In case that link doesn't work, here's the YouTube link:     And another 15 minutes to find this clip out of Glenn Beck's video - the first few seconds is all the corporate media will allow the public to see, since the low IQ people will think Trump said " I love inflation ", and that was the end of it. Taken WAY out of context! Here's that part, plus the 2nd part about the oil smuggling operation:

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.
