It is my understanding that Corsa exhausts are also made to order, meaning they don't have exhaust kits just sitting on the shelf collecting dust until they sell. When you place your order then they make the exhaust.
Yes, I found this out after ordering as well.

I ordered from CSPRacing and had it in 3 days, appeared to be drop-shipped from Corsa directly. They were the cheapest I could find.

Good luck with your install! I’m 99% sure the GM performance exhaust is a rebranded Borla, but certainly could be mistaken.

When the dealer tech installed my Corsa, he said he had to remove the lower control arm temporarily and drop the spare tire. @Fast_AT4 can probably confirm if he needed to.

Just the sway bar ends and spare tire need to be removed when installing the Corsa Sport cat back syste. It's fairly easy, took less that 45 min to remove the old and install the new one.

I also added the Corsa resonators a week after install to give it a deeper tone (which I like a lot better).

I have a 5.3 and don't have the quad exhaust. Not sure if I want to do the quad exhaust conversion. I think the dual tip dump out the rear passenger wheel is too low to the ground. I'm considering just getting a Corsa Pro Series muffler and Corsa tip and getting a turn down exhaust dump setup. Muffler and tip would be $500-ish plus the labor...

Not sure where everyone lives but I’m in the greater Seattle area. Ordered the 6.2L Corsa setup for my 2023 XL AT4 and will be looking to sell my factory exhaust if someone wants to do the OEM conversion from side to quad rear.

Info on the Corsa resonators? Will be installing mine soon and may want to go with a deeper tone.

It is quieter. The resonators are 2-3 dB quieter.
