I installed a flowmaster super 10 series which they said is their loudest muffler. I  left the V4 flap and deleted  resonator. Ive had this new set up for 2 months now and there is quite a difference. I plan on taking out the V4 flap because at low rpms it makes the exhaust hiss a little, ( it does sound like a exchaust leak but I've had many people look at it and they say there no leak and that hissing noise is the v4 flap opening and closing. But driving around in tow mode takes that problem away and definitely turned heads. 

 

I hope this was somewhat helpful. 

 

I plan on going this weekend to have the Flowmaster 10 Series installed.. First just the muffler, start it and see how it sounds with the resonator in place.. if not to my liking then ill have them remove it.

But where is this V4 flap? is that inline somewhere in the exhaust?  Is that a job for the muffler shop? what does removing it do?

Depending on what year your truck is it'll be in front of the muffler of behind it. If you crawl under your truck you'll be able to see it.

Went first thing saturday morning :)  had them just install the muffler in place with everything else as it was and started it up, sounded ok, but really couldnt tell it was a 10 series at all, so had them remove resonator and flap and just dump it.. MAN what a difference.. def alot of drone in the cab, but only at certain speeds/RPM ranges.. but i love it.. more than the 40 series i had on my 15.

If i were you, id have them remove the resonator, keeping the resonator on keeps the truck sounding like its still stock. 

 

And the v4 valve is inline with the exhaust, located after the muffler. Any muffler shop can remove it, all they have to do is cut it off and weld in a new piece of piping. By removing the v4 valve it makes the truck sound alot better and takes away the hissing noise.

Is there any value to our OEM Exhaust once it is removed? I took mine off at less than 2k miles and couldn't bring myself to let them "just scrap it", however I'm not really sure if I have the room to just keep it around the house either. It still has the Chrome/Polished tip and the V4 flapper and everything else utilized with the stock setup.

ANybody have the CORSA dB exhaust single exit? I’m looking to get that for my 2017 5.3L but nervous about the V4 mode sound issues in general when replacing the stock exhaust. I’m assuming by installing any exhaust system that replaces the stock muffler, the V4 flap is removed? Also it says that the CORSA dB is made of T409 steel so I don’t understand why people on here are saying that it’s made of a lesser grade steel

I believe the Corsa is made from 409 stainless and the dB is made from 439 stainless.

I believe the entire Corsa Sport system is 304SS with double tip, and the dB is a 304SS muffler and single tip but 409SS tubing. The tip and muffler look great on my dB, but the tubing has surface rust.

How long have you had the exhaust on your truck for? And what area of the country do you live in?

I actually bought it used and have had it on my truck for almost two years. I live in Ohio and drive it daily all year round.

Anyone on here have the MBRP cat back? I have a Magnaflow 12909? 22" muffler, left the flapper ( zero drone) and resonator but it's too quiet. I can get the MBRP for $322 right now and if it's too loud for long family trips towing I can swap it back. I'm so ready to pull the trigger soon how it's "black Friday" lol.
I want a deep, powerful sound and not raspy and poppy. The videos I've watched make it out to be what I want.. I'm just nervous it will be too loud.

      2021 suburban RST - acting up/lights flickering

      By 520Zilla · Posted

      Hi all,   I just bought a 2021 suburban RST with 88,000 miles on it and everything has been good but I’ve been noticing within the last month or so that there are small electrical things going on and I know what the AGM batteries and all the electric electrical in these big trucks you need to have a constant flow with good voltage   That being said, I bought a new battery thinking that that might have something to do with it but today I went to get in and start it and it said no key found when I had the key right in my pocket   It also proceeded to flash the lights inside and outside for over 30 minutes as I went to disconnect the battery as soon as I touch the negative terminal, I heard the relay reset and everything come back up. I got in the truck and started it no problem.   Anyone else have this happen to them? I’m starting to think it’s the KARR system that the dealer installed short circuit stuff.

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      I don't drive this truck on a regular basis since I have a new company truck with no out of pocket fuel or maintenance cost. Yesterday I got it out to run some errands and got the title message on my DCI. A quick Google search suggested to first clean the Map Sensor. I pulled it out and it was sooty so cleaned it up and reinstalled it. Issue not resolved. My OBDII is a couple years old so didn't see any codes. Today I took it to a friend at AutoZone to get him to check it with his reader. It had the following codes: P20C3 P02BB P221F Stating the most likely solution is to replace diesel emission fluid (DEF) tank assembly.   So, I guess a trip to the dealer is necessary. I read where there was a backorder on these tank assemblies several years ago so hope that has been resolved.

      Do you keep your tires at full capacity? 80psi

      By Chuck FB · Posted

      Are you using a weight distribution hitch system with your trailer as that alone can change the actual tire pressure requirements needed. It would prove interesting to see what the actual individual axle weights are on your truck when you are hooked up to the trailer. In fact when your hooked to the trailer, typically if anything unless it has a large capacity weight distribution system that is over cranked, often the weight on the front axle will be less when hooked up vs driving empty and certainly if one doesn't have a weight distribution hitch. Really the only times one may get up there with weight on the steer axle is if there was a snow plow mounted on the front or a motorcycle on a rack or with a very large jockey tank full of fuel at the front of the box that transfers a bit of its weight to the front axle.    And of course your tires carry more weight for a given tire pressure due to their size vs a stock sized tire so there is that to take into the equation as well.

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.
