Im sure it is one of the many threads on here, but mind showing me a picture of how you "Clamped the flapper open"?

 

Yes please! Have been looking for this myself.

I agree 100%. I love the sound of a Chevy V8. I've had 5 (progressively louder) mufflers on this truck and I finally got the one that sounds GOOD. Flowmaster Series 10.

 

Stock muff = Prius

Magnaflow 18 = Impala

Magnaflow 14 = A little better

Flowmaster 44 = Quite a bit better

Flowmaster 10 = FINALLY

 

It will never be as loud as my Vette, but I like it LOUD. :thumbs::thumbs::thumbs:

 

(My wife calls me "The 60 year old teenager)... ... ... :crackup::crackup::crackup:

How did you run your exhaust? Cause mine SI/SO 3" pipe all the way with no resonator and flapper is still pretty quiet. Very very minimal drone and would like a little more sound. I had my pipe ran just like the 6.0 on the 2500.

Got it done yesterday. Much much better I just wish it were a little louder.

 

The clamp of the flapper is what made the big difference. It makes it much louder.

Im probably getting flowmaster 40 series or super 40 series i have no idea whoch ones ive been listening to as some people just say 40 series.

 

Looking on their site i dont see anything 2.75 though so would i buy 2.5" and have them weld to make it fit or buy bigger at 3"?

 

Also are our truck center in center out?

I didn't buy a Flowmaster but I bought my Carven at 3". I was told in this forum that it's better to go bigger with the 3" then going to small with the 2.5". Hope that helps you.

No flapper, no Rez, Flowmaster 10, 3" over axle and discharge in stock location behind RR wheel. I also hollowed out the third cat. My friend has a lift. Disconnected the pipe, pulled it out of the way, then drilled about 50 holes in the Catalyst with a concrete bit. Banged on it with a hammer and chisel. (safety glasses) Big chunks fell out.

Thanks our set ups are the same minus the cat. Maybe that'll bring me some volume.

I would have just had the remove everything from the muffler back and bend up a new tail pipe.

Can post a video on how it sounds? Just curious because I'm looking for a good exhaust for my 2015 V6 Sierra.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      By Black02Silverado · Posted

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
