Does anyone think it would be possible to have 2 exhaust options? By this I mean cut the exhaust system just before the muffler and put in an electric cut out, from the cut out, run one way to the muffler #1 (this one would be a more tame exhaust sound) and then the other exit for the cutout would go to a much less tamed, much louder muffler, muffler #2. For these purposes lets say that muffler #1 would be an 18" or 22" magnaflow, and muffler #2 would be a 14" magnaflow or a super 40 series American thunder from Flowmaster. After the mufflers, the pipes from each would them run to the same exhaust tip(s).

 

It's something I have been wondering about. I mean, we all have those times where you don't want to wake up everyone in the neighborhood or in your house becuase you are leaving early morning so you would want your truck to be a bit more on the quiet side, while at other times you are wanting your truck to just shut down anyone else who tries to roll up next to you and rev their exhaust at you.

 

Anyone think this would be something worth trying? After I get everything else done that I want to do to my truck, I may try this. Unless someone already has and had a bad experience.

Corvettes have what is called "Dual Mode" Exhaust. There is a butterfly valve in the 2 outside tips (4 total), that can be controlled by a remote (Called "Mild to Wild" Controller). The valves are controlled by a vacuum line, either open or closed. Closed = quiet rumble... Open = Ground pounder. Pretty cool system.

 

Not impossible to rig up on a truck, but it would take a lot of custom work!

The number of hours spent on any given forum are directly proportional to the number of dollars spent on subject vehicle.   Ask me how I know.

So I can anyone with the Corsa side outlet exhaust comment on the sound and drone (if any) in V-4 mode on the highway and around town? I'm very close to purchasing one but I can't find many reviews of the exhaust system. Thanks in advance!

Go to a muffler shop have a y pipe put in front of the muffler run a dual pipe with two exits. Weld header flanges on the tips with wing nuts, wild and mild. You could even run the wild side in front of the rear tire. You don't really have to flange the quiet side, you open the loud side it will just flow that way. Ive done it, its a blast.

Is there a way to control that from inside of the cab?

Yes, electric cut off. It doesn't take long to undo three wing nuts. Caution where gloves when hot.

Thanks man. After I do a few other things to my truck I'll probably do this mod. I've been thinking about it for quite some time but knowing that some others have done it before makes me want to try it more haha. But as I said, this one will be after a few things. Tint, lift, tires, light bar. After those mods, it looks like I may have a real "true dual" exhaust. But not how most people think of true duals haha.

Drone is terrible with my 14" magnaflow. Thinking about buying that AFM delete device from Range Technology. Plug n play and can remove when you want the AFM for long trips and what not. Its 200 bucks though.

Do not waste your money. All you have to do is shift your trans into Manual mode(I use M5 mostly) .and the truck will not switch to V4. Works great.The new trannys are not really "MANUAL" shift any longer. It will run thru first to fifth just like normal. and when you get on the highway ,flip the little switch on the shift lever to 6th and everyones happy. Just remember to flip the switch every time to M5 or you'll take off in first gear. After a few weeks it will become second nature and you won't even realize your doing it. It will seem like a different truck. Hope this helps. OH I forgot to tell you that when you do flip the switch to 6th the truck will go into V4. And be shure to use the switch and not the shift lever . Don't want to go shifting into reverse at 70 mph. :driving:

Its shifts right at red line too, sometimes on the 1-2 shift it bounces the red limiter, pretty cool. I don't go into m6 till after 60, no change in gas millage.

I just want something that is gonna sound good, with a nice growl, not be too loud on idle, and absolutely will NOT drone in V4 mode....there are so many choices. Anyone have suggestions?

 

I've heard good things on Corsa and Borla cat backs. And they are guaranteed no-drone.

Corsa if you have the dough.. aFe if you like your wallet fatter. I had the corsa on my 05 and loved it. Also, now am running the aFe on my 14 and love it. Helicopter sound is there when switching from V4 to V8 but in town I run it in m5 like everyone suggests. On the highway there is no drone but get on the gas and you can tell its there.

      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.
