Muffler Advice


Recommended Posts

I have a 2021 6.2 Chevy Silverado, and just did a muffler and flapper delete. Sounds amazing but is way to loud on the highway and drones way too much for me. I am wanting to put a muffler back on but I want one that is as loud as I can get with no drone. I was looking at the Flowmaster 50 Delta Flow, the 40 series delta flow, or a Magnaflow 22 inch muffler... I am wondering the pros and cons of all of these, if they drone, and how loud they really are. I have watched a bunch of Youtube videos on them and they just don't do a justice for how loud the drone is. If you guys have any other suggestions for what to put on there I am open! Thank you!

Some people claim there’s mail order exhaust that eliminates drone. I haven’t witnessed the noise changing magic yet. With cylinder deactivation engines the exhaust sounds are going to change. The modern idea today with true duals is adding an equalizing cross over. A drone maker. I’ve been doing duals on my rides since the 70s. The best sound in my opinion is unequal exhaust (no cross over) 21/4- 21/2 exhaust and glass packs. Yes I’ll sacrifice a few ponies for the sound. The cheapest way if it’s still possible. Shut off the cylinder deactivation put the muffler of your choice. Exhaust noise or music is a personal thing.

I've got a 3" 26" long Jones Muffler *coughnotaMagnaflowbecauseitisn'tstampedMagnaflowcough* on my Silverado 5.3L 8 speed.  Eliminated the flapper too.  There is a tiny bit of drone at certain throttle conditions around 40mph when it seems like the truck is sitting between gears.  It's not terrible and it's a speed I rarely seem to maintain on surface roads.  98% of the time I have no issues and at highway speeds it isn't even noticeable.  I drive 45 minutes on the highway each way 3-4 days a week.

Black Widow Venom 250 is what I have on my 15 6.2L.

Also had the flapper and resonater cut out.   V4 drone can get annoying when city cruising and also when cruising 55-60mph.

 

Quiet on the highway whether you're going 70 or 85.

When you drive on the highway is there any drone at all… with my current setup on the highway it can get so loud at certain rpms that it can interfere with conversations. I want it to sound good but I also want to be able to have conversations without yelling inside…

It does NOT drone on the highway no matter if you're going 65mph or 85mph.  My truck does around 1700-1800rpm.  You get very little sound from it. 

 

When I tow my pontoon, a lot of times I leave it in M7 so it's not going in and out of 8th.  In 7th it's doing like 2200 rpm I think at highway speed and you hear it for sure then,  however I wouldn't say it's a drone as much as it is just the sound of the exhaust under load. 

 

 

My past experience with drone was an Avalanche with a Flowmaster 40 - good lord that was not fun on the highway.

      I’m looking for the best 6 inch lift for this truck. I talked to a local suspension shop for an install and they spooked me on Rough Country - they stopped installing them due to poor quality and many after install problems.
      would very much appreciate any and all input - truck is a brand new build and I want to do it right.

      Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle. 
       
      The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
       
      The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
       
      Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!

      Hey Everybody. I’m about to have my 2014 Silverado AFM deleted with stage 3 cam upgrade, longtube headers, l86 intake, l86 TB, 3200 stall, custom tune. My question- is their other things I must do to go with these upgrades? Truck is 4x4 but will soon be lowered. Driveshaft? New Trans cooler? Bigger oil pump? Any help would be appreciated. Thanks in advance

      I have a 2017 Chevy Silverado and I have been having trouble with the entire radio and screen .. I recently replace a bad HMI module that I got from infotainment.com and it solved the issue. Now the screen is back to black and the display where the gauges are says “audio off” any idea why ?? Anyone have this issue I tried everything. Maybe I need a new ACM module now? HELP !

      Opening this up to disabled and other Vets. We need a place to share. Isolation is death and not a good death. 
      How are my Brother and Sisters making it work? I’m struggling tonight. I’ve done a lot and overcome much. As I age the pain is overwhelming. 62 YO  90% disabled  VA combat vet of USNavy and USArmy.   Never asked for help and for 42 years have helped others.  My truck, the science of automotive technology helps me maintain my sanity. Any others here that feel the drain on the soul and body? My fingers and formally strac functions don’t function right anymore.  I love the constitutional basis of USA but wonder have many forgotten the rule of law? UCMJ? Caring about others before self?
