Someone in these Escalade forums has a very - very - recent set of videos on the Escalade dealer installed CORSA catback. Search a few pages of Escalade threads. It's either a 2020, 2021. or 2022 model.

Welcome to the Funny Farm !!!

 

I believe Corsa sounds totally different compared to GM performance exhaust. GM Performance Exhaust sounds closer to Borla performance, which has a deeper sound and not too loud.

Corsa is louder at WOT and has a more exotic sound.

This is the closest example on YouTube.

The Corsa and Borla are quite significantly louder in all aspects than the GM system, especially Corsa. The GM exhaust is supposedly built by Borla but side by sides of Borla Touring and GM Performance showed that the GM was tamer - this is on the K1 Silverado/GMC 6.2s.

I saw the Corsa video that was recently posted and it does sound awesome but quite a lot louder than I’m looking for for an Escalade. I’ve done some good searching and I am not finding any sound results and very few firsthand experience with the 21+ Escalade with the GM Performance exhaust.

 

I will take some videos in next couple days of gm performance

 

Do you have it on your vehicle/have you heard it in person?

 

Noice!

 

Well shit I’ll have to fix it on the morning

 

GM Performance exhaust

 

Sounds super classy. Love it!

I have a 22 Escalade with the sport exhaust and it sounds great at a cold start if your outside the Escalade. Besides that it's a dud and a waste of money. I will be upgrading to the Corsa.

 

I've gone the full cat-back exhaust route before, but this time, considering the 'Sclade already has stainless steel exhaust, I went the muffler route only. My local exhaust Pro recommended a Canada brand called "Flo-Pro." The chambered internal design is similar to Flowmaster, which means no sound change as it "burns in." I'm using their "Big Oval" series and I absolutely love it. Nice low rumble around town that goes nearly silent on the freeway. Perfect!

Wish I had been smart enough to do that. Didn’t even consider muffler only. Definitely would have been cheaper. Duh.
