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!

effing brilliant...never knew this existed and came across your video...

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.

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.

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!

I just used 2 ZipTies to hold it open. It takes a little "finagling" and a lot of patience... but it works.

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.

@Canadian587 Жыл бұрын

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.

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

Exactly I would just keep it how it is

@anthonymason701 Жыл бұрын

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

Cut it out if your doing a new exhaust.

@@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

@tp2315 Жыл бұрын

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 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.

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.

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?

@Fatalisticperformanceinc 4 ай бұрын

Just use your best judgement bro, if exhaust is traveling down the pipe just remember the exhaust flap opens with pressure
