This still with the stock muffler? I'm thinking of deleting the muffler and flapper on mine today, Thanks in advance!

[YQatari]

^ Yes, stock mufflers.

Fixed mine today with a hose clamp. If I start shitting money then I will eventually get a new muffler and have it deleted at the same time.

 

Of further note, I have the 6.2 and my dad's 2011 Denali sounds 100x's meaner than this truck. Pathetic.

Do either of you who removed/binded/restricted etc.. the "flapper" open notice the AFM 4 cylinder mode louder/drone now? Especially curious with those with the 6.2L

Nope, none whatsover! Clamp that sucker. It gives a nice lil note.

What Dave said... whats it going to hurt anyway, just put a $2 hose clamp on it for now and see if you like it. If you don't... crawl back underneath it and take 30 seconds to pull it back off. Its hard to go by what people think actually sounds good and the name Justin Bieber pretty much sums that statement up.

What size clamp do I need? 3"? 4"?

I would get a 5 or 6" from Home Depot, hell you could lock it down with a 2" clamp just wrapped around the two square heads on the valve end, its just a little harder to hold when you do it but not impossible by any means.

I did the same hose clamp method on my camaro. They put this bs valve on the convertibles. The rattle of it opening and closing sounds like garbage. Problem solved Lways open sounds great

I like the hose clamp idea. Cheap and easy to try and if you don't like it take it off.

The crappy valve was causing a whistling sound to come out of my exhaust pipe when I pushed on the gas pedal at lower rpm's. Took it to the stealership to get it fixed and they said there was nothing wrong. Pissed me off because the noise reminded me exactly of the commercial where the guys motorcycle sounded like a weed eater. Lolol. Not the sound you wanna hear from a 6.2. Clamped it and now no more whistle.

Clamped mine yesterday....it sounds much better w/ the muffler delete. The truck also feels like it's holding the gears better.

 

I also pulled 24.4 MPG 22 mile trip last night. The highway mileage on this thing is awesome to be a truck.

I'm assuming you're 5.3? Just took my 6.2 for a 800 mile trip and the best I could average from texas to Louisiana was 19.2 MPG with the cruise set at 75 mph.

Yeah I'm 5.3L w/ 3.42's and that was at 65mph. Seems to be about my sweet spot.

[440hsp]

Gotcha.. wish I could achieve that kind of mileage without only being able to drive 60 mph. Lol
