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.

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

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

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

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!!

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

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.

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 !

Sounds amazing either way but definitely a lot more whistle afterwards

You’re so handy man. I would never have the patience to do all this myself

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

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.

😂 My friend and I are teaching our boys how it's easier to get to the bolts by removing stuff that's in the way rather than suffering because of laziness. Thanks

Great videos man, keep up the good work!

Wow that is a very noticeable difference

I was shocked at the difference too, wow that’s a nice sound!! Lol

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

Nice video. Several years ago I put on my federal emissions standard lb7 piece of cake .

Good video! Maybe try mounting the camera stationary. It would give a wider view and be easier to follow than the close up quick movements. Very informative man, keep up the good work

That thing sounds good

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

Great Videos!! You definitely deserve MORE subscribers than you have now!

If you ever plan on selling that truck. I want first dibs lol Truck is LIT!

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

magnetic 1/4 swivel sockets are out on the market now grey 9712umg is the metric set

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

Awesome video bro! Love that sound.

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

Damn it sounds great!!! I was going to buy one a while back , but Mr.Banks had talked about it in one of his videos and he said it wasn’t a good idea, never the less I think I am going to get one now lol

Now this isn't a deleted truck right? that sounds amazing

Was this video before or after you deleted it?

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

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

There's only one stud under that hood...🔥

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

Any idea why the recommend tuning on the PCV reroute intake horn vs the one that retains the factory location?

Awesome video bro🙌🏼

Does it void any warranties for the truck? I just got my L5p.

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

Mine doesn't sound like that, I don't know what the problem is, I really followed all your instructions and I also used the same thing as you, do you have any idea what the problem is and thanks friend

Rolling in money

I have a stealth tune in my LP5 I want to get more whistle sound. Thinking about S&b intake plus this tube. Should I re route or use the same factory tube and keep it routed the factor way?

what a legend

Did my intake horn same time as batmowheel. Really whistles loud now. Probably more to do with the batmowheel

Great video, thank you.

Got a link for that top side creeper? That thing would be so handy

Is your truck deleted or is the DPF still on it?

I've got a stock 18 l5p, I'm wanting to put that intake horn on my truck by I've heard it might throw a code, any idea what code it'll throw. I don't really wanna keep the pcv hose connected to the intake I'd rather re route it

Crazy that I had to buy a whole new intake setup because they wouldn’t just sell me the hose. Now I have money sitting here doing nothing

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

Did you get any performance bonuses HP or MPG?

I seen in your video a oil filler tube extension on your truck. Where did you get that part?

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

Idk why they changed the design and put the inlet back on for the oil.

Have you seen any turbo surge since changing the intake horn?

My 2018 is stock and I don't p;an on any mods BUT I would like to hear some turbo. Is this video the result of solely the Intake horn? Thanks.

Awesome !!

I'm looking to do this also but was told a Tune is recommended, did you have to tune yours? any issues?

Stock exhaust? Tunes? Deleted? Or all stock

Does that turbo horn fit a 2024 duramax? Also does it affect the warranty?

At this point in your build was the rest of the truck stock exhaust and intake ?

Will this mod void the warranty

Just saw your video on your install of the intake horn I have a question did you get the better whistle on a stock exhaust??

Sweet video bro

Love the content! Where do you get one of those ladders?

Denny can you drop a link to where to order the hose and intake horn together at? Not finding it on wherli site sir.

can this be done on a stock no tune l5p

I can do the re route without a delete right?

What do you think about changing the original air intake ? On a 21 model thanks

Anybody know where to find one with the pcv reroute? Been looking for a few weeks and it seems they don't sell them anymore only selling with the pcv port. Do you think you could cap off the port with rubber cap? Or too much pressure...

Where do you order these parts from?

Part number for the horn and reroute kit?

It's interesting to see this cause I recently installed the Wehrli horn and intake tube on mine and noticed zero sound difference.

Subscribed bud.

I made a 4” intake tube for my 2020 Chevy Silverado 2500HD to delete the intake muffler & resonator. No lights on dash 🤟🏽. I’m wondering if the intake horn you installed is a 4” on the upper side? I asked cuz the factory intake horn is a 4”

Great content and explanation!

Is this truck deleted?

Do you have oem turbo

I know this video was posted a yr ago but I just watched it. I have a 2021 L5P and was wondering if this would work on my truck?

How did you rotate the hose?

Is that intake horn from wehrli also? I cant find one on their site without the port

Must be nice to have a deleted truck... oh how I wish hahaa

🔥🔥

Will doing this to a stock truck cause any service lights to go on?

Can I do a pcv reroute on a stock truck and just plug the original intake horn?

Gotta take this off that off and so on like I’m about to say hell with Chevy and buy a Cummins

you aren’t picking up hp from a pcv reroute whoever told you that has a screw woose lol

Could I put banks air intake on if I do this?

Can this be done on a 20+ truck without problems

Love the videos I’m about to hit you up on insta for some questions

Was the turbo stock in this video?

I have a 2020 Denali L5P. How did you get your exhaust to sound so good? I’m new to the diesel world. I have a a basic understanding of the DEF system but everything I’m running into says I can’t touch the exhaust system without having issues.

Could you let us know the dimensions of the cap for the factory turbo horn, so we can do this with all of the factory parts? Also do you think it will cause the factory ECU to go crazy with no shop work?

Do you notice any compression changes?

Is it deleted

wow duramaxs suck to work on

Can you not talk so much and just show the damn results 🎉

The sound before and after are not either one they're not the same truck or you've got your truck deleted in the second sounding one because there's no way that the truck is that much difference
