Here is what mine sounds like with the muffler and flapper delete... the second truck in the video is the 2019 with the exhaust screens still in place...  Based on how it sounds now, would it make sense to cover them up?  I feel like it is loud, and those being there might be the reason why there is zero cabin drone while cruising, compared to the first truck in the video, my 2018, that does have a decent drone...

Thoughts?

The Resonance Free Pipe (RFP) takes the place of a traditional resonator with much less weight and bulk. Some vehicle applications however still use resonators. An RFP works by venting a small amount

Just for your information: it’s an empty pipe, which has holes to break the pipe resonances (standing acoustic waves within the pipe). The patches are for reducing the generation of further noise

I have exhaust clamps that I will be installing soon on a fully stock exhaust. I want to see how this sounds until I can buy my Borla S type system.

Covered my single outlet exhaust using 2.75" Exhaust sleeves (link below) on my 2020 Chevy Silverado with 5.3 V8. Here are three sound clips with stock, 2 mesh resonators covered, and 3 mesh resonators covered. I purchased the exhaust sleeves on amazon for about $10 a piece.

 

Here's a video with sound clips of stock, 2 front mesh resonators covered and all 3 covered:

Just wanted to chime in and say covering the mesh screens makes a huge difference. I recently swapped my factory muffler out for a Dynomax ultraflow and deleted the flapper valve and it was still surprisingly quiet unless you really got on it. Those mesh screens work really at muffling the exhaust. Cold starts are pretty rowdy now haha.

I just muffler swapped my OEM for the Borla S-Type on my 2020 LTZ yesterday. While doing so I also removed the flapper valve. Unfortunately I was really upset when I first started it up. The swap did not produce the sound that I was looking/hoping for. It does have a nice deep growl to it, especially at cold start. Once it warms and dies down you can barely hear it's even there unless you get after it, and even then it's nothing too aggressive. I regret not going after the Borla Atak. I will however to covering those mesh screens and hopefully that helps.

 

The sound the Borla S-Type added is amazing, it has a very nice deep tone to it. My only issue is that it  isn't very loud. I really hope the covered mesh screen give me that volume i'm looking for and then the swap will be perfect for me. If that doesn't work i will for sure be getting the Atak installed.

You sir are the G.O.A.T lol, those sleeves from Amazon fit over the screens as if they were made for them. I purchased 3 but did not install the 3rd one furthest to the rear because I wouldn't have been able to cover it completely due to the exhaust hanger and it would bother my OCD. I can't believe the sound difference. Maybe only 10-20% louder but at least 50% deeper in tone. Came home while the wife was getting groceries out of her SUV and reved it a few times. Her response was "WOW I can't believe that actually made a difference" haha. Best $20 mod ever.

 

Edit: What exhaust tip is that? Thanks

Thanks man!  I’m glad it worked out so well for you!! I agree that third one back is frustrating because it’s right next to that hanger. It is pretty cool that it makes that deeper tone.

I covered my screens with band clamps from Amazon and clamped the flapper valve open a number of months ago.  The sound improvement was just what I was looking for.  No drone, but a little more sound and deeper tone.  If you want an exhaust that is loud, this will not make you happy.  I tried it first with the tape before spending the $60 on clamps. Just my thoughts. I am considering removing the flapper valve all together.

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      Navigating senior years.

      By garagerog · Posted

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
