CORSA EXHAUST Problem... Calling all corsa trucks!

Nicholas La Croix · April 6, 2016

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

Nick

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.

I'll try taking the tips off, hopefully resolve this.

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.

Do you have an aftermarket intake on your truck?

Nicholas La Croix · April 8, 2016

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:
