This was great. You did a hella job. I just pick up my truck . 2022 chevy trailboss 6.2 and the sound from factory leaves much to be desired. I've done my oil changes changed my brakes small stuff like that. Well you've given me the motivation to try to DYI this. Going with the kooks headers and the quad tip borla attak. Your truck sounds bad ass bro.

[@TheCortezChannel.]

You're going to love the Kooks headers! Thank you for the kind words, it was a bit of a hassle trying to record at the same time but I knew it would be worth it if someone watched my video.

I'm late posting this but thanks for sharing this install. Clean and to the point. How's it holding up?

[@Max_ellis74]

I would support it where the studs are point down on the trans.

[@DIgoon10]

You haven't mentioned if you reused the factory head gaskets. Or do you have a link on where to get it? Great job by tye way!

[@TheCortezChannel.]

I bought new OEM manifold gaskets to use during the install. Thanks for watching! 🤙 🙏

@@TheCortezChannel. Did you use plug wire sleeves at all or a heat wrap of some sort? Also can you link the OEM Gasket?

[@Im_DJ_1]

What exhaust do you have on the truck? Ive got Borla Exhaust Type S and love them. No drone. Also do you know if these parts are CARB compliant? Im in Cali, and they pushing CARB compliance hard. Makes it difficult to do any upgrades.

[@TheCortezChannel.]

I have the Texas Speed & Performance catback exhaust. Check out my install video. Kooks does offer a catted Y pipe for emissions testing.

[@juniorshallow7468]

Any lights on the dash since the installation? And what's the difference if you gutted bank 1 and 2 catalytic converter?

[@TheCortezChannel.]

No lights on the dash whatsoever except the gas light lol

[@lilmarv398]

Have you experienced any header tick while driving? I did headers to my 2012 and the tick was fairly noticeable while the engine was under load, I now have a 2018 and am curious before I decide to do it again. Awesome truck btw, I have a white all terrain just like yours with the 6.2.

[@TheCortezChannel.]

Yes you can definitely here the direct injection a bit more with the headers.

[@ccooper04]

What size lift happens to be on your truck and tire size? Mine sits to low for my liking and I like room to change oil. Way mine sits right now it’s a pain to get under it and zero room to move.

[@TheCortezChannel.]

The truck came with a 3.5" knuckle lift from RC when I purchased it.

[@StevenPfeiffer]

How is the trans holding up?

[@davisbutler53]

Hey boss do you have any fuel smell in the truck when driving? I’m really on the fence for catted vs non catted. Was thinking about pairing a whipple supercharger on my 6.2 Silverado as well…daily driver

[@TheCortezChannel.]

Yes I do slightly smell the 🌽 every once in a while. Not unbearable but yes non catted will definitely allow the smell of fuel

[@TheCortezChannel.]

I personally love the smell of burned 🌽 lol

[@AlcatrezM16]

Did you get a check engine light on after install before the tune? Or not since you didn’t delete o2 sensors

[@TheCortezChannel.]

Yes I did but after the tune it was removed.

[@jaredmarincel4109]

How’s the drone when you’re cruising? I have long tubes with no cats and an mbrp cat back and I wanna change out the mbrp

[@TheCortezChannel.]

No drone whatsoever. Highly recommend the TSP catback. The integrated cutout is a plus!

Did you reuse your factory gaskets or the ones that came with the headers? And did it say ACEL without a tune

[@dansherwood9851]

Set a cel. Stupid phone.

[@TheCortezChannel.]

I bought brand new OE gaskets for the install and yes I had a cel light on. Once tuned it turned off

[@misfit5.3]

How is the oil catch can? how often do you clean it out and are you going to upgrade to 6 ounces?

[@TheCortezChannel.]

The catch can has been working perfectly. I'll empty it about every oil change. The plan is to upgrade to the 6oz I just haven't gotten to ordering it yet. Thanks for watching! 🤙

[@JorgeMorales-il4fi]

did tuner tune tcm too? shes moving! i just got done installing a circle d 32-34 stall on my high country 8l90 transmission i heard i have to get tcm tuned to mess with shift points

[@JorgeMorales-il4fi]

i had got mines ecm tuned and shift points where the same and tuner even said they couldn’t add the tow haul button to downshift ig not yet on the 8 speeds did u deal with the same? did tow haul worked after tcm tune?

[@tlive1710]

Very informative video, thanks for all the free advice. Your truck is 🔥🔥 definitely 👍& sub

[@craigerking9790]

how much of a difference would you say you feel over it stock , with the headers and intake and all

[@TheCortezChannel.]

There's definitely a huge difference with all the mods done. With the TCM unlocked & tuned shift points & firmness are great!

[@brianroberts9647]

That looks sick installed on your truck. I am ordering these myself to add to mine. How long do you think it took you total time w/o the rain interruption?

[@TheCortezChannel.]

I believe Kooks has a Black Friday sale going on, I'd check to save a few bucks. It took me about 5-6 hours if I'm not mistaken. It was my 1st time installing headers so I took my time.

I haven’t really found anyone that is doing mods to these trucks on KZbin that I would like to do such as the mods you are doing to your truck. I watched your ZR1 LT5 throttle body install- great idea. I am trying to find someone where I live that can port my intake and runners as well.

is there a difference between the longtube and the regular kooks headers?

If you're talking about a difference in long tube vs short tube headers there is a difference. Typically short tube headers shine low to mid range and long tube shines mid to high range.

[@jeremybrady7835]

Are headers worth it? And does it make the truck super loud even with the muffler?

[@TheCortezChannel.]

Headers are 100% worth it. After installing header the truck will obviously be louder but there are some exhaust systems that can quite it down. Some people even install headers and keep the factory catback exhaust.

[@AlfredoLT]

Did they make your truck throw the check engine light

[@TheCortezChannel.]

Yes, I deleted the rear O2s. Once tuned the check engine light turned off.

[@marceloesquivel5665]

How U plug in the o2 senors

[@TheCortezChannel.]

I plugged them into the factory harness. For the rear o2 sensors I used plugs to seal the holes on the y pipe

[@PissDrunxVato]

Would this fit in the GMC/Silverado 2021 5.3/6.2 models????

[@TheCortezChannel.]

I am not sure about that. Reach out to Kooks Customer Service for more info. I do know tuning for 19+ is way more expensive than the previous Gen 14-18

[@tlive1710]

Any estimates on tuning for the 2015 Sierra SLT 6.2L after long tube installed? Any issues w/problematic lifters, I've only done generic tune/programmer to shutoff /delete AFM/DOD full- time V8.

Was there any check engine lights with stock o2 sensors? Also are they completely stretched out yo make the connections?

I did have a check engine light come on because I deleted the rear o2 sensors. During tuning they removed the check engine light. Factory wires were long enough to reach the bungs on the headers.

[@Usawrestling113]

@@TheCortezChannel. ok so all 4 connections will reach just fine with no check engine light. How come you deleted the rear o2 sensors? Any specific reason?

@@Usawrestling113 with Kooks yes. I had no issues with the o2 sensors not reaching the bungs. I can't speak the same for any other brand header.

@@Usawrestling113 as far as to why I can't tell you much aside from what my tuner told me. There's no need for the rears because I have no cats.

[@baja1102343]

Rear O2 sensors are only used for catalytic efficiency, now that they are removed there’s no reason to have them on. They will cause a engine light from the cats being remove.
