I had a Corsa Touring Cat Back a few years ago on my Yukon and loved it.  Awesome, throaty sound on acceleration and quiet while cruising.  My new AT4 came with the GM Performance Exhaust which is the Borla exhaust.  It sounds ok, but is much quieter than I was expecting.  If I had a choice I would go with the Corsa.  It definitely sounded better.  And FWIW, I prefer a quiet exhaust, but the Borla is too quiet if you want a performance exhaust.  I only got the GMPE on this truck because I had no choice.

GM accessories/parts exhausts specify Borla for most systems, however they offer another  exhaust that doesn’t state the brand, that one is made for GM by Corsa. It is similar to Corsa touring, possibly even quieter, however a little more more growl than oem. I had this dealer installed at delivery on my 2017 6.2 for $1195, all top quality components. I purchased a 2023 LT Trail Boss 6.2 yesterday and see basically the same exhaust however with more piping mimicking oem to connect to twin oem HDMI tips. I can’t recall exactly but it lists for over $2k. These are made for GM by Corsa without the Corsa designation but people familiar with Corsa will recognize the components and quality.
