All right I am ready to order a set of headers I just can't make my mind up between the kooks with a catted y pipe or the doug thorley tri y headers with the ORY pipe. I do not have much experience with headers other that the ARH headers I had on my 2013 5.0 mustang. I have found a lot of info on the tri y headers on older body style trucks but can't find much on the kooks. Both of the ones I am looking at have 1 3/4" primaries. Anyone with experience that can give me a comparison between the 2? I am willing to spend the extra money for the Kooks but really don't want to if the benefits aren't there. Keep in mind mine is not a race truck; 6" lift, 35" tires and 4.56 gears. Possibility of supercharging down the road.

 

Thanks for any advice.

Both are great quality pieces. The biggest advantage the kooks have is the catted Y. Cats can always be added to the ORY.

 

I haven't seen back to back Dyno numbers, but the low end torque is supposed to be better with the Tri Y design. That's part of the reason Justin talked me into those since I pull a lot.

Thanks for the feed back. Yea the mid to low range torque is supposed to be great on the tri y headers and I am about 90% set on going that route. Did they come with the gaskets and header bolts and did you order them through BB?. I have a price from Jarrad with BB for them but just havent completely made my mind up. I am having a hard time figuring out if the kooks are comparrable low to mid range. I know top end they should have the advantage but I am very seldom in that range

Did you ever end up ordering headers?

+1 on Michael Drain's question ^^^^

 

I plan to put headers on either before or after I lift mine, more likely before or at the same time that I get the lift. I have heard good things about the Doug Thorleys on the old bodies.

 

How much are y'all finding the Doug Thorley long tube headers for? I am seeing between $700-800 for the parts. Is this a good price? Never done headers before so idk what a good price would be

Ha smart man! I miss my duramax.

I sure do love this one. My 12 was a problem child with emissions issues but not all were plagued with them and the new one seems great right now. Just popped the regen cherry at 715 miles; the 12 would have had 3 already by this time. Time will tell though.

I don't plan on racing my truck but am looking at th Doug Thorley tri y headers. No plans for adding cats to it. Does anyone have a price or review on them? Reading some reviews on Autoanything seem promising with claims of better low end torque, strong quality for the price, better sound, and some claim increases in MPG. I'm planning on headers around Christmas for better power since I will be lifting this summer.

 

Would really like to head some reviews of them on a K2!

 

Also what's a good price for install? I don't plan to install them myself.

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
