A little late to the truck game got one like yours but Holly crap your sounds perfect, serious power too!

somewhere in one of them porchs........ "elsie!! that young whipper snapper is out with his new truck again"......"i know ethan,i can hear him dear"

I hope these motors catch as much success as the gen 1 , 2 , 3 and 4 . They look like there great motors.

Damn it, people, please, please quit wasting your money on bullgarbage products like throttle body spacers, that are supposed to spiral the air. There is way too much research already proving that it doesn't work. Only on some carberated intakes do spacers sometimes help, if the carb is too close to the base of the intake, so that the airfuel mixture cannot mist, before pooling by hitting the bottom of the intake, then these spacers, help, not the spiraling either. Do you know how many abrupt changes and cuts and corners the air has to go around in a modern fuel injected engine. Yes sometimes spiraling works on straight through shots like on a Harley Davidson carb, that goes straight into the motor. These examples are few and far inbetween. It just pisses me off to again see someone help make wealthy these asses passing false information and lies to rip off hard working people. It helps the sound, are you kidding me. Otherwise thanks for attempting to pass on information.

Thanks for this video. I got the 2016 sierra 5.3 yesterday and I too was thinkig of buying the k&n cold air, now im convinced! I know I will love that sound. I might not need to change the exhaust.

I have a cold air intake and long tube headers and honestly I don't notice a difference other than great sound and looks awesome.. :)

delete the resonator i did it to mine and dont regret it. gave it it a deeper throaty noise than with just the muffler off

I'm running a F5 chip. cold air intake and a TBS on my 05 tahoe every little bit counts muffler delete up next its alot better than it was Just my opinion

Expensive cold air intake (200-500 are a waste of money. I paid 100bucks for mine and it looks and feels great (all metal). I also had a cam and longtube headers installed. Next is the converter and centrifugal supercharger.

Hating, hating, hating, IAM sure the cold air intake & exhaust alone made significant power difference and better acceleration on take offs . Hater's will always hate .lol

If you add a performance mass air flow sensor it will run alot better, jet power flo mass air flow sensor

Spacer is just to allow your engine more volume in the intake plenum to help burn more efficiently. No hp gain to real talk about! All spacers whistle, they are designed that way, if you drive yours easy you will hear it too!

The only thing missing is the 20 dollar "mass air cheater chip" lol

Sounds awesome. Now I know what I'm gonna do to mine.

It's sounded good before but it's way better after

my 14 is straight piped. I left the resonator in but have removed it since then. I left the valve in but I'm going to remove it as well because it rattles a bit. The straight pipe does sound pretty good and with 3 cats there is no need to worry about back pressure. I am going to tune it though and delete that stupid 8-4 cylinder garbage.

Borla attk is best exhaust for these 5.3, they have a video for every exhaust u can do on KZfaq

Hate hate hate. Do what you want its your money. Truck sounds nice

I did notice that it did make the shifts louder.

Big waste of money....next time you wanna throw money away send it to me! RT

interesting they suggested a muffler delete. that was my plan on mine, ended up w the super 40 muffler instead

Your truck sounds good in general

I love these trucks! Can’t wait to be able to afford one lol I own a 06 Titan that’s pretty quick would love to see a race between the two

"HEY, HOW LONG TIL WE GET TO THE MALL!" "WHAT! !??" "THE MALL!!! HOW FAR???!!" "I CAN'T HEAR YOU. .TELL ME WHEN WE GET TO THE MALL!!!"

Cold air intakes!! Has anyone ever check the actual temp before and after the replacement from there stock induction, to "cold air" intakes?? I have checked more than 15 different makes and models of vehicles, using temperature probes in the induction air tubes, on 4 cyl, 6 cyl and V-8's and they all come up the same outcome. Your cold air intakes, actually run hotter, some more than 80 degrees hotter from the air cleaner to the throttle body, than the factory induction systems. Unless you wrap the "tube" with some type of non-conducting heat barrier, i.e. HVAC wrap, you are getting under hood engine temps. Also, unless you get the air induction from outside the vehicle, you are getting under hood engine heat. This is why when you usually see people running wheel dyno pulls on there vehicles, the hood is usually open, or big fans in front of there grill, to cool the incoming air into the engine and to cool the engine compartment. Ya, its sounds pretty cool, but they really don't work, unless you wrap and route them properly. Throttle body spacers?? That little 1/2 inch spacer (1-2 cfm's) isn't worth $1.00. The amount of "extra air" (thickness of the plate) you gain going into the upper intake, doesn't amount to nothing. IMO, waste of good money.

Hi I have a 5.3l v8 2014 Silverado. I know I'm a pro at air flow for vehicles. The spacer will do very minimal gain(like 0.5 more hp&tq). But if you add other gaining mods like a cai, exhaust, and more air flow directing to the cai. It will all domino-effect(which means all the mods you do will work together). At this point the spacer would probably do 3-4 hp&tq gain

I put k&n on mine, and replaced the muffler with a magnaflow, i cant hear the magnaflow over the intake now. These vids dont do justice to the sound they make in the cab, very nice growl when hoping on the highway.

You lost all creditibility when u said throttle body spacer.....😂😂😂😂😂😂😂

Hey I just want to know what is throttle body spacer fit on a V6 truck 4.3 so 2017 a 5.3 spacer can it fit a 4.3

personally I've never had any whistle at full throttle. the whistle is most pronounced at quarter throttle where I'd like to call the "sweet spot." I've always thought it was geared towards giving more torque for everyday driving, which it does imho and to help find that "sweet spot" it give you an audible que, ie a whistle. maybe it's a placebo effect, but I felt I could keep it at QUARTER THROTTLE and "feel" the whistle, adding torque so much so that keeping my foot there would have the truck easily finding +60mph from 3rd quite smoothly. imho it added something these engines lost along the way... torque!

A CAI won't do anything for performance unless you also add a tune. A TBS is a complete waste of time & especially money.

That TBS is absolutely pointless if you have a Vortec manifold.

I like the way it sounds before

Did you really notice that much of a difference with the spacer? I have the cold air. Stock muffler. Just wanted to know if the spacer would gain anything? Let me know if it's worth it or not... Thanks.

people asking what he got for mpg? he aint gonna get any driving around like that!

ofcourse a muffler delete sounds better than a flowmaster. i wouldnt put a flowmaster on my lawnmower. Go borla catback. you wont regret it

Nice vid. I agree that the TBS won't do much. I got suckered into one on my old Dodge and other than giving me an annoying whistle, it did nothing. I just got a 2017 Sierra and I'm doing the intake. I am super interested in the muffler mod. Did you really just cut the muffler out? Also, are you from Canada? I swear your driving in the Collingwood area here. :)

how's the sound inside the cabin during cruising speeds 60-80mph with the muffler delete??? is it a quite sound VS a loud sound like if you would have flowmasters???

Great video 👍

I made a CAI out of PVC Pipe for around 10 dollars.

instead of throttle body spacers. look into porting and polishing throttle body.

If your asking for my 2 cents worth? It seemed to have more torque before! You were spinning the tires pretty good before the downgrades! Spacer plates only work for naturally aspirated engines, from my experience anyway. $300 + for a cold air intake pipe is really another waste of money. You actually get colder airflow from the factory setup because the air is actually coming in from the front of the vehicle. Cold air intake sucks air from the HOT engine compartment so it deletes the purpose right?

Waste of money my friend absolutely no gain but sounds good. All I did with my 17 High Country 6.2L was drop in a AEM dry Performance filter in stock box and Airaid intake tube.

I got the 5.3 also just not 4x4 but I have long tube headers k&n dyno tune and a magnaflow ...sux that I dnt put pics up on here lol

Sounds good to me.

So before I end up getting a spacer I have a 2011 5.3 v8 silverado with knn intake straight pipe and tune will it make a difference??? Thanks in advanced

Put cam in it.

Next time put your money towards long tube headers then you will hear the difference

I didn't see or hear the difference before and after the so call modification... waste of money.

The muffler delete may make power, the other crap is a waste, spend money on a tune or tuner instead

Cam it, and put a stall in, then you will see a huge difference! But nice truck man

what made you go with k&n? I ask because I've had k&n in previous trucks and liked it, but I'm really liking bully dogs CAI. just trying to be as informed as possible. I too have a 2015 5.3

Hey, did you have your truck chipped? I like the shift points, but they are different than mine. Just wondering if you changed the shift points. Thanks

TBS's are a waste of money. Better off filling your tank with premium fuel. No gains are made from a TBS.

Great video, thanks for putting it onto youtube.I was wondering re: the upgrades that you did, are these relatively inexpensive upgrades? I'm new to all this and would like to get a bit better performance out of my 2015 GMC SIERRA AT 5.3l . Thanks.

Looks less powerful down low. I think the reduced back pressure move the powerband up a bit.

I like it

Hey what kind of mpg gains have you got?

Did any of the mods help or hurt gas mileage???

What ever happened to u guys streaming on twitch

What kind of program did you use to edit your intro video clip??

What upgrade was done to the motor?

waisted your money on a throttle body spacer. multi point or direct direct injection vehicles don't benefit from extra space in the intake.

Seems like it was slower after.

did you take the truck to Dino to confirm the difference in hp yust wondering?

did you upgrade the MAF ? point less to have a CAI with a stock MAF they wont handle the air intake.

Bro u could have just done a 6.2 intake and throttle body and called it a day and the sad part is it would be cheaper

I dont know if you know this but dyno proven on these motors that the throttle body spacer hurts power.

Truck sounds nice. How much was the k&n?

What rpm is it shifting at, the max engine speed is 5800 rpm according to General Motors

Just buy a camshaft

just muffler delete? for exhaust

Will taking the resonator off affect anything like reliability wise?

My bro has been running one for years. Cold air intake just keeps cooking map sensors on him. Curious s to what these mods do for your warranty haha

So you talked to the muffler guy ,,,, that’s 15.00 an hr flunky ok I believe it now.

Do you even race bro? Haha. I was telling Jeremy that you were gonna do a review on your truck at some point, and what do you know. 😂

What’s your MPG now ??

hey why did u go with k&n and how is it holding up ?

What I wanna know is where did you get that dash cover haha its nice.

cause i love everyone DAMN IT.

any improvement in mpg?

Will you be coming back for bo3 and will you get a ps4?

you in NW Indiana?

Buy a 6.2 liter if you want real HP and torque gains.

The only thing the air intakes work on are diesels

Won't pass smog in California

have you felt any vibrations at 70-80 in this truck like some people say there are??

spacer and K&N do nothing

TBS is paper weight.

Is traction control off?

No HP increase. Just noise. It stimulates the brain. Makes you think the money you spent did something. Let’s see track #s OH you’re Just looking for sound? Hmm I guess I’m just hating then, Sorry. I Thought you were a performance Guy

It literally sounds worse.

You paid cash to loose HP. Lol

Wht the fk is that noise?

Another kid wasting money on an aftermarket part but doesn't work with that intake. Sits at home stays on his computer looking for parts that says that will make your truck go faster. I wonder how much Daddy paid for that truck.

That thing is a turd 💩

1: a "CAI" doesn't provide a gain of anything except tone under the hood 2: throttle body spacers are for suckers Thanks for making a stupid video. I enjoyed the giggles.

hey why did u go with k&n and how is it holding up ?
