Flapper is on the outlet of the muffler. It's a square little box on a shaft. There is a spring inside the square part to snap the valve shut when there is low or no flow.

I realized I know nothing about modern exhausts. I guess the good old days of the pre-70s c10 are long gone. Crawling under my truck made it real. The 'flapper' thing I thought would be easy to locate. I was wrong. Maybe I'm looking in the wrong spots. Someone make this easier please!! I was going to do it myself but I'm strongly rethinking that

From the front...flex pipe...muffler...adaptive valve (aka flapper) just aft of muffler...and then resonator...and finally, tail pipe. You can see the resonator by looking toward the frame in the rear passenger side wheel well. Another way to. Look at it is the "flapper" is between the muffler and resonator in the stock exhaust.

I hear that is a good choice...just chop off from before muffler back and put in the Maggie with new tail pipe and tip. I did the GM Borla and love it. Good luck...

Has anybody installed a Carven R Series yet? I received mine today. I was shocked to see how small it is. There is almost no baffling. I have attached a few pictures.

 

How loud do y'all think this will be?

Da fuq? That has a solid and a perforated orrifice plate and that's it? That's going to be insanely loud. There is no dampening media whatsoever

I had it installed today. I cut off the "flapper" and left the resonator on. I don't think it's very loud. Not very noticeable at idle and a little more while driving. I am going to see how I like it this week and possibly have the resonator removed.

With the resonator in along with the rest of the stock piping and cats a chunk of pipe in place of the muffler isn't crazy loud either. I really don't see much in the way of noise dampening from an orifice plate and edge of a witches hat lol.

I had GM put the Borla on before i picked up the truck. Not insanely loud but nice rumble.

Does anyone know if dB Perfomance plans to release a cat back for 2014+ Silverado/Sierra 5.3? I love the sound of the Corsa system but would prefer not to pay $900 if I could get a dB Performance system for $550.

Want to hear the Carven after it's installed.. Not sure on the flow of that thing though? Nice and open, with some strange baffling. If you look at a magnaflow race they are open the whole way with a perforated core.

Just had a Gibson cat back installed on my 15 Sierra. I was worried it would be a little too loud but am pleasantly surprised. The tone is great under load and is hardly noticeable at idle.

Which one did you get? How is the drone/chopper?

Got the single exit system. Part # 615628. Autoanything.com had it on sale for 30% off when I purchased it. The drone/chopper isn't all that bad. Before I would just feel it, now I hear it.

    • 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.
    • 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. 
    • 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.
    • I have 2 choices. 
    • 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.
