Does An INTAKE HORN Really Give Your Truck More WHISTLE?

Love the vids. You're one of the few youtubers that actually goes in depth and elaborates on what you're doing.

Sweet! I just stepped in to a 2020 myself from an old 2006 LBZ. Went from an insane whistle to zero! Nice video!

[@bdickey0581]

Doing the same thing as you. Did you ever get any sound.

[@claytoncooke1980]

@@bdickey0581 no sir, not yet. Haven't done anything yet, but am getting my tuned ECM Tuesday the 8th. (Tomorrow) Can't wait! All I really care about is having that power as I did with the last truck.

WOW that’s a huge difference!!!!! I’m shocked too! That sounds amazing!! Keep it up man, loving the content!

thanks man

Great build, and great info. You keep it real, none of that filler bs. These are the videos worth watching/saving for my own build. Great content!!

This is exactly what I was looking for and hoping to gain. Ordered an intake horn from Rudy’s Diesel earlier today for my 2024.

[@bryanspanjer3213]

I noticed more buildings around to reflect the sound back to you on the second drive. That makes a big difference

[@neverenough7767]

GM definitely has hands down had the best sounding vgt turbos . I’m a cummins guy . Only thing I can compare to that sound is my 2nd gen swaps

[@DennyDiesel]

Yessir.

[@duvielhernandez2887]

Love your videos buddy. I think that a magnet 13mm socket is the best to remove the intake horn bolts.

[@StillLiveWithMyMom]

Love your videos man, completely underrated. I just joined the L5p family so keep it up 🤙🏼

Nice to see you changed your tires and rims now it looks like a truck !

Would it make a difference and be worth it if running stock?

[@enochstutzman8017]

Sounds amazing either way but definitely a lot more whistle afterwards

[@DennyDiesel]

Haha for sure

[@frankcastillo4647]

Hey gents. Decided to do this to my 21 2500 Duramax High Country. And I agree with most of y’all, it’s that 4th ac bolt that was the bane of my existence. Just now my dudes, there is no shortcut to it. Box wrench, turn not even a quarter inch, flip, repeat… took hours. Putting it back-- remember to do that bolt first!!! Or you might puncture that line!! Top it all off, don’t feel like it made any difference. But also, I didn’t do that pcv reroute either… not sure - but hope it works for y’all! Love this cat.

[@lilesnate]

Didn't make difference on my 18 l5p. Made my truck have compressor surge now

[@lilesnate]

Not worth money

[@bmallett09]

@@lilesnatedid the same thing to mine. I grinded out the intake horn so it’s completely open then ordered the antisurge ring from duramaxtuner. I haven’t had surge since

[@cole-trickle50]

Getting the AC compressor bolts out and back in was the hardest part for me . Everything else went fairly smoothly . Used the electrical tape on the socket and extension to help not lose them . Also did that with the nuts when I installed them . Time to install the hot and cold side pipes next

[@samueldamianreyes7602]

Bro what tools did you use? I can’t figure out how to get to the damn back left bolt off of the ax compressor. Gah gam

[@cole-trickle50]

@@samueldamianreyes7602 I used hand wrenches and I will admit it is a tedious and frustrating process . Gotta turn the bolt flip the wrench , turn the bolt flip the wrench and on and on . Putting it back on was a little bit of a PITA but I got it done . The rest of it was fairly easy

[@samueldamianreyes7602]

@@cole-trickle50 about how long did it take you? I spent about two hours today trying to figure it out. Ended up putting everything back together. Figured I’d get a stubby set of wrenches and try again. I just couldn’t fit the ones I had in that space.

Thanks buddy!

[@chrisgilliam8294]

I just bought a new 2020 Sierra AT4. This is my first diesel and love it so far. I don't really keep vehicles for very long so I don't know if i'll be tuning, but I would definitely like to get more whistle out of this thing. Would I benefit from this on a 100% stock truck? And is there anything else that can be done to free up the breathing of this thing without affecting the truck or warranty? Thanks for the vids

[@ultraclassic3033]

Good work, and great videos on l5ps. I have a deleted 2018 silverado 3500 l5p. Would like to know how bad the smell is from pvc reroute on the l5p? I've done this on my lbz and ran down the frame a little further with slices in the hose and mad sure the hose slopes down the hole length as for in cold weather in canada this will freeze and you can blow gaskets

[@Peter-r1q5c]

Just to confirm, the sound after install is achieved by just an air intake and turbo horn? Thats wild if thats the case!

[@nadianicolae6485]

CAN YOU PLEASE explain the benefit in long run for rerouting the PCV valve . Thank you

[@mitchellmetcalf6499]

Nice install video man very detailed and I was very shocked by the difference it ended up making now I know what to tell my customers Thanks

[@EmmittMAKNHP]

Awesome video bro! Love that sound.

[@joe0813]

The PCV just doesn't connect anywhere on the other side?? Also they dont have the reroute kit on their website anymore. Or the intake horn without the pvc port on the horn

[@waltmeachumjr3057]

Do you need a tune for this mod? I would love to do this intake horn.

[@Subi_doo]

The manufacturer of this says no.

[@auclair331]

To do this, will you need a tune? I want to do this but haven’t tuned it yet. Don’t want to throw any codes but hate having the PCV dump into the turbo

[@jasongrinnell1986]

That sounds awesome. Awesome video. Thanks for the lesson. Lol

@Denny Diesel, I just (like 2 days ago) bought a new 2020 Silverado 3500 HC. Does doing this void out the factory warranty?

[@Subi_doo]

Probably... but who’s going to know of you remove it before you need to claim warranty 👍

[@Subi_doo]

I’m in the same boat, I just place an order for a new 2021 GMC Sierra 3500 crew cab long bed AT4 for $83k and I do not want to void warranty. You’ll be fine as long as you don’t have a problem removing it before you take it into the dealership.

[@SpachHVAC]

Is your truck tuned? Wehrli says has to be tuned to run the re route.. I have l5p adding the Derringer tuner with exhaust. Should I run the same one u have here or the horn that connects back to factory pcv? Thanks man

[@DennyDiesel]

Hey man my truck is tuned. I think they recommend that to cover them selfs but I THINK it could be done without a tune.

It doesn't look that hard and he was stopping to explain things while filming. GM probably figured you;re going to service the AC before the intake horn.
