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.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
