I just picked up my 2020 2500HD with the Duramax on Friday.  After 500 miles I feel

compelled to upgrade the sound of the truck.  It is altogether too quiet.  I’m not looking to be the obnoxious attention-seeking jerk, but I do want the truck to make a bit of an impression.  
 

I’ve never owned a diesel, not have I ever added aftermarket exhaust to a truck.  Do’s or dont’s from personal experience out there?  What does or does not void warranty?

Good luck with the new E mission standards on these trucks there's not much out there to improve the sound with an aftermarket exhaust set up Sent from my SM-A705U using Tapatalk

The mbrp exhaust adds nothing but looks. There is no sound difference no HP gains. I was told this directly by mbrp. It's for looks. Due to all the diesel restrictions this is what they have. I had on

Not sure what kind of gains or sounds they will get you, but Banks Power will be releasing their ram air intake and monster exhaust around November.

MBRP pro series DPF back is out and on my truck. Sounds great! Also ordered the new S&B intake. Was released yesterday. 

Do you have a video of the exhaust? I’d like to hear it, been looking around for some options.

I had one on my 6.2 gasser and loved it. Banks has something coming out soon. Gonna wait and see what they put out but not spending $400 for nothing but a shiny piece of exhaust that adds nothing

Yep nothing will change the sound unless you drop the emissions system, its doable but expensive and very few people will tell you where and what to do.

Yeah, that's why I want a video since the poster claimed the sound was "great".  I am skeptical until proven otherwise.

That’s laughable and nonsense. There are many options for different sounds and volume. Even performance cars have exhaust that change their sound by simply stepping on the gas. Others by flipping a switch or turning a switch. All while maintaining emissions.

Ummm, today’s diesels, it’s a VERY complex exhaust system. Back in 2016, I was looking at exhaust systems for my DMax, come to find out, yes, it can be done but just how far is the question as you don’t want to damage anything cause the full original factory exhaust system was quoted to cost somewhere in the neighborhood of $11K to replace. Get underneath your truck and check it out, lots of technology now in these trucks, thanks to the EPA.

You clearly don't know what you're talking about.  DPF has completely change the landscape from an exhaust standpoint.  Hence my interest in substantiating any claims for sound improvements or noise level.

Are you looking to delete you exhaust system or just change out the muffler?

I have no interest in performing a DPF delete, the poster above made it seem like a DPF-back was providing a change in sound which - for the third time - seems incredibly unlikely.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
