Nope, never resolved it,

 

Got told it is a sound the motor produces

Dumb question...Do you have a throttle body spacer?

I had a whistle from my Corsa at full throttle I sent a video to Corsa and they shipped a new muffler next day air and fixed the problem

They sent me a new muffler also but it didn't fix a thing

TB spacers are known to cause a pretty loud whistle from my experience. Have you tried the soap and water trick? Just mix up a spray bottle of dish soap and water and spray around everything to find any leaks. Obviously doing this on a cold system would be the best.

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.

 

Did you ever find a fix for this? My truck is making the same whistle sound with the corsa

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.
