I'm finishing up my coffee and heading out to chop off the HUGE muffler and replace with the muffler delete by MBRP. I too will be leaving flapper valve for now and then possibly do the spring mod to keep it open. Likely I'll run with this until I save up some sheckles for the full cat back. Truck sounds great man, nice job!

Greetings from a fellow Silverado owner in Travis County. That sounds good. I have a 2021 RST 5.3L

How proud your neighbors must be

Great Video and Project! Subscribed from Brazoria County!

Sounds much better! Just bought a 6.2L TB looking into this .

Nice vid def gonna try this on my TrailBoss too, thanks Thor

Not sure what that costs but my local exhaust guy does muffler deletes for $60 plus tax. He will take the flapper valve out too, make a new piece of pipe, and weld it in. Takes like 20 minutes once the truck is in the air. Your truck sounds good. Now it sounds like a proper V8.

Had a muffler shop remove the muffler and flapper on our 6.2L. Left the rear resonators in place. Sounds amazing and only cost me $100.

This must me the replacement for the totaled Jeep. Very nice choice there.

I just ordered mine and plan on keeping the valve. I want it to sound better than stock, but not too obnoxious.

Appreciate it! One of the best videos I’ve seen on this. 1 question: do you ever see your self changing it to Borla or AWE 0FG?

Biden would not be happy with this mod...sounds great

Did the same with and without the flapper cut out. Sounds 100x better with the flapper cut out also. Best sound tho is to cut muffler out and weld a 4” tip angled at the ground.

I'll be doing this in the upcoming week to my 2020, tired of the "quiet", need the rumble like my camaro, thanks for the great video,.

Let’s see some more videos on the truck!

💪

Nice notes, I like it ! Now you have to bring back the roar of a quadra-jet carb sucking in gallons of air ! LFOD !

Wow thats not a muffler thats a suitcase i dont blame you Bro.

Is there drone with towing? I’m wondering with you leaving the flapper, if that is the reason you don’t have drone with regular driving without towing. But I’m curious if you have drone if you were to tow a camper. I do long trips with a camper and drone would drive me crazy. Love the sound!

My home is 1/4 mile from a Texas State Highway. When we moved here 6 years ago it was tranquil. Now, the highway has been widened and traffic has increased 10-fold. To make matters worse, in the middle of the night and early in the morning, I am jarred awake in my bedroom from the noise of every truck, car, and motorcycle that have 'deleted' mufflers. I thought they put mufflers on vehicles for a reason.

I have a trailboss. I could never hear it idle until I deleted it.

Do you have any issues passing the state inspections for Texas?

Sounds good! , Does this void your warranty?

Thinking about doing the same on my 5.3L. How's it sound at highway speeds? Did you notice any difference in performance?

Sounds good. Now get rid of the USB port exhaust tips.

Can you leave the 4 inches on the back end and cut the flapped out with this delete pipe?

Did you keep your resonator near your rear axle ?

I'm going tomorrow to get a Flowmaster 40 or Super 40 installed on '23 RST, had the same thing on a '20 RST. I wish I could hear the muffler delete in person. How is the MD on the interstate?

If I cut closer to the muffler on the opposite side of the flapper valve will the AFE Muffler delete be able remove the the flapper valve ?

This one time at band clamp.. I got two girlfriends!

This may sound like a stupid question but what is drone noise, I've never heard that phrase before

Hey man I’m interested in getting the same delete, do you still recommend ? Have you had any issues?

Just curious if you have the 5.3 or the 6.2? A lot of exhausts I'm finding are saying they're for 3" exhausts, when the exhaust on my 5.3 is 2.75". Has me hesitant on ordering them if they're not gonna fit.

Any drone at highway speeds?

Fellow Texan here. Great video. This might be a silly question, but does this mod affect manufacturer warranty at all by chance?

I’ve cut off the muffler and the flapper and the drone is just too much. How’s yours with the drone?

How bad would this affect the tuning of the engine?

What are the dbs at idle?

How about the drone sound

How does it sound inside while driving?

Did your engine light flash ?

Dose it void warranty

Does this effect fuel mileage and performance?

Is it road legal? Like noise compliance?

Does your fuel tank not have a skid plate or am I loosing it?

How loud is inside the truck?

Why keep the flapper thing

Conroe?

I believe you were supposed to cut the flapper off

I removed it and put a cherry bomb on it lol

Would of been nice to hear it revved up.... lmao lmao. But ok.

cut that damn flapper off too.

Rev it up WTH.

Guys, to muffler delete and retain the stupid gM flapper valve is pointless. It's like putting your hand over your mouth and breathe through your fingers. Useless.
