Fix the annoying or sqeaky exhaust flapper noise on your vehicle! This was done on a 2018 silverado 1500 LT #chevrolet #exhaust #gmc #chevroletsilverado
I’ve recently developed the chirping noise at start up in my Suburban. I’m active in an online group so I knew what it was. After seeing so many videos about hose clamps, I stumbled across yours and man, you are a lifesaver. It took me 2 minutes and the chirp is gone. Plus, as an added bonus, cold starts and acceleration sound way better. Now, it’s time for a Flowmaster. Thanks man!
Thank you dude.. I was looking into my throttle cable, tensioners, etc trying to figure out what the f the chirping sound was.. Mine is on start up and when accelerating. This is exactly what it is. Gonna order a AFM disabler and crack the flapper valve open. Much appreciated. Saved me some sleep on this one lol
Nice this was my question. I have warranty still and ordered a paradox muffler to install. I already have a boost AFM disabler so I guess I’ll rig the flap open in case I need to make it stock later on.
Thank you!!! Just did mine today!! Stock exhaust, 2022 5.3, covered resonator screens, I’ll drive it a bit and if we need more than we’ll just have to replace the muffler!!!😁😁😁
This worked perfectly for me. Unfortunately the replacement was too small (made for 5.3, not 6.2). Ended cutting it off and getting a bigger pipe. Fucking sounds awesome with a muffler & flapper delete.
With the flapper held open or removed completely, you can hear a drone... depending on your system, it isnt too bad. Almost sounds like a subaru lugging at low-RPM
I swapped the factory muffler for a CherryBomb Salute SA1229 is the part number. I took the flapper out when i did. I dont even notice the drone unless i listen for it, or if the radio is off. It isnt really that bad. I noticed a significant increase to mpg and also better performance (could just be my mind... spent money, so that makes it quicker) but i know before if i punched it from a roll, it would chirp the tires. Now it light them up hard enough that traction control engages and ruins the party
@@DrDennis i did. Lost the third cat in a boating accident, 3" axle dump with the CherryBomb salute, s&b closed box CAI, and a tune on a 2018 silverado (to disable AFM [until i can afford a proper delete, thank you JB], modify the TC lock-up and trans shift points, along with cleaning up the factory calibrations) and she woke right up
I don’t mind mine operating as designed. My problem is, mine was seized and I can’t get it to operate freely. I suspect it has been stuck open, but I didn’t mark it before I freed it up. I think carbon is restricting movement, and there is n way to remove the carbon in the pipe. Guessing I’ll have to rig it open. Clockwise to full open, right?
Not sure how the hell you was able to push that spring in and twist it to that other section, but I tried for ever with no luck. I ended up holding the flapper open and putting a small hose clamp around it and tightened it down. Doesn't move at all.
I believe you went the wrong direction. Counter clockwise should be fully open and clockwise gives you a partial open. You should be able to see this work when you have someone rev the engine while you’re watching. There is a video with a cutoff muffler you can watch this as well.
I need more info on the squeak you heard.. specifically was it only when you accelerate.. how long would you say the squeak lasted mine sounds like a little turbo blowoff valve whistle.
I did this but I’m honestly not sure I turned it the right way. It is locked when I try to twist one way and twisted a good amount the other way. Is it possible for it to get stuck closed?

I know this is a bit older, but you’re my hero. Bought a ‘23 that was chirping occasionally, and did this and it helped. Thanks, man!
@@theodoreroman glad the video helped man!
I cut mine right off when I swapped mufflers, sounds beautiful in or out of AFM mode. Yeah there’s a rumbly drone on the freeway but I like it.
effing brilliant...never knew this existed and came across your video...

Hahahah i like that idea😂
Why didn't you just cut the flapper off when you put the new muffler on?
Thank you for your time man!!! Been wondering if there was a simple way to do exactly this. Excellent job!!
Glad i can help man!

Good on explaining the situation.
Thank bro! I was about to use hose clamps later on today. Love this!
Better to use clamps I think, when you slide the spring tab, it’ll be open when idled, but drive then it’s possible it’ll be closed.
Yea man glad i could help!
Thanks, did this yesterday!
I cut eveyrhing even the valve
Very helpful thank you sir!
Thanks for the video!
You bet!
I just used 2 ZipTies to hold it open.
It takes a little "finagling" and a lot of patience... but it works.
Plastic zip ties?

On my truck there was 9hp difference when opened on dyno if you have it tuned for v8
Turn it to the front of the truck basically

Exactly I would just keep it how it is

Cut it out if your doing a new exhaust.

No drone on mine.
Good info, Thanks!

Thanks ❤
Thanks, mine was stuck closed
Thanks mine a 2018 whistles a mother Fker and I’m pretty sure that thanks bud

At rest its between the two.
Might this help to get rid of a P0430?🤔
My truck got tuned and now runs on V8 mode only and some time after that I started getting the P-code.
Not sure man ive recieved no codes on my vehicle but i think its worth a shot!
I need more info on the squeak you heard.. specifically was it only when you accelerate.. how long would you say the squeak lasted mine sounds like a little turbo blowoff valve whistle.
Only on acceleration really
Can you remove the flapper like completely if you put a full exhaust?
Yes
After this is done will it not spin in either direction?
Asking because mine doesn't spin at all so I'm thinking someone already did this
Yea once this is done its fixed in that position
I did this but I’m honestly not sure I turned it the right way. It is locked when I try to twist one way and twisted a good amount the other way. Is it possible for it to get stuck closed?
Just use your best judgement bro, if exhaust is traveling down the pipe just remember the exhaust flap opens with pressure
Can just remove mine or will i get codeson dashboard
You will get no codes👍🏼
Ok but when you drive, it’ll go in the closed position? 🤔
Not a chance. Its completely locked open man
EPA strikes again, unelected bureaucrats deciding what’s best
It's designed to lower exhaust sound at idle or low rpm. Emissions (EPA) have nothing to do with the valve.
