So I have a 2015 Silverado with the 5.3 motor. Just wanted to get a little more sound out of it so I purchased a Corsa Cat-Back exhaust. Got the exhaust, installation was a breeze in the truck sounded amazing. That didn't last long... Started getting this whistling sound while I was putting a load on the motor. I rechecked all the clamps, everything is seated and sealed nice. Corsa sent me a new muffler, but no dice, still whistling. Corsa is now telling me that it is a sound produced by the motor, and there is nothing I am going to be able to do...

 

Someone please tell me that can't be true.

 

It's a 2015 Silverado with the 5.3...

 

The truck sounds amazing, but I can't stand getting on the freeway and wanted to give it little gas and getting this twistle ish sound.

 

 

Thanks in advance

Here's a video, sucks but for some reason video struggles to get it. Play it a couple times and you'll pick up on it.

My truck has a little whistle to it. Nothing crazy but it sounds like a tiny turbo... I have a stock 2015 Silverado 5.3.

Cant tell much from the video. But I have Corsa, and I don't hear any whistle.

But it could be the tips. Maybe try taking the tip off and see if it still does it.

Yea they sent me a new muffler and still didn't resolve the issue. Haha typical

i worked my way back removing the tips, to the muffler, all the way to the spherical clamp.

 

fired up the truck and gave it a couple revs, and the whistle sound was still present... I cant believe it.

 

Am i getting the whistle because the Corsa system is so free flowing?

 

I am thoroughly disappointed.

Yes I have an airraid intake. I even removed the intake and I still got the whistle through the exhaust. I love love love the corsa sound. Just don't love the whistle that I hear now.

dunno what to tell you man. Ive never heard any whistle with my Corsa, and still cant pick it out in your video. Your truck sounds exactly like mine. Here are some of my exhaust videos:

Yea it's weird, if you were to hear it in person, you would without a doubt pick it up

    • Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today
    • 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?
