Anyone tried just covering the mesh "resonators" on the stock exhaust with the factory muffler?  kind of curious how much of a difference that would make.  

 

I want the new corsa system BAD, but am having a really hard time justifying spending that much on exhaust

The 6.2 has normal style glass pack shaped resonators. At least mine did. Thought only the 5.3 has the mesh...

I've been wanting someone to do this.... 

 

I already have a Magnaflow installed and have been experimenting with covering the resonators.  The difference is surprising!  With them all open the sound is actually quieter than stock except during heave throttle.  Idle is very very quiet.  With them all covered it's much louder, more like I expected,  but I experienced some drone when AFM took the engine to 4 cyl or less.  Currently I have just the 2 rear mesh holes covered (there are 6 total) and I can hear the exhaust, no drone, but I think I want it a little louder.  Still experimenting with it.  I'm driving a few days every time I change things around.

 

I've found the easiest thing to do is to cover the holes with muffler tape.  It's an aluminum high heat tape with fiberglass reinforcement to make it stronger.  It peels right off when you want it to and if there is adhesive left on the mesh a quick pass with a razorblade clears that up.  The roll I got fits right over the mesh hole, so you can't tell it's there (you can see the exhaust from the wheelwells).  Nice and clean.

Hey this sounds like a good idea! I have the 5.3 and stock exhaust. It sounds pretty nice actually to me but sometimes I do crave just a little more like in the old 5.3 with the last resonator removed.

Just covered the back 2 (figured the lowest frequency) very little difference.

Covered the all six now slightly louder than stock - no drone yet.

I covered all 6 of my resonators with aluminum tape.

 

It is slightly louder than stock at idle and I can actually hear the exhaust while driving.

Think it was worth it after you were done? I see you are running duratacs. On my 16 my duratacs would drown out the sound of the borla system. When I put summer street tires on the exhaust seemed much louder as I could hear the exhaust not the tire hum.

Are you saying that by placing the 20 Gauge Aluminum with Stainless Steel tie wraps that it wasn't worth it? I was thinking of doing this to my truck rather than going the whole route of placing a Super 44 Flowmaster in and cutting out the rest..... or were you just stating that the durtracs weren't a factor in sound displacement compared to the exhaust?

@Limelight what brand of tape did you use? Does it hold up for very long? I have heard that it is only a temp solution that should be used.... with you being out of MD did you use it in winter conditions?

Is there any exhaust leak sound since it’s not air tight or is it?

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      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.
