After reading through previous posts, I see mention of the new oil from Mobile 1. Has anyone been running this for awhile?
Lastly, looking to upgrade the exhaust, any recommendations? I love the crackles and pops of the factory exhaust on track mode but it's just too quiet for my taste.
I see MBRP has exhausts listed for up to the 2018, but when I called them they stated it wont' fit the 2019. Has something changed with the exhaust in 2019 or have they just not "confirmed" fitment. Open to suggestions on exhaust, cat-back for now, not looking to headers at this time.

Your car should already have been factory filled with the 0W-40 ESP since it is a 2019. Pop the hood and check what the oil cap says. It's great stuff and there's no reason not to run it as far as I'm concerned. You will only find the 500/1500 mile oil change recommend in the GM performance prep manual, which doesn't come with the cars but is available on the internet. Also, while I was at Spring Mountain, a place that owns over 100 performance GM cars including dozens of Z06s and ZL1s, they said they do a 500/1500 mile oil/diff change on every car, they consider it mandatory and have seen better results when they've done so.
As for exhausts, I would stick with AWE Touring (Don't let the name fool you, it's loud and aggressive) or Corsa (Same story). Don't get a cheap exhaust that's going to rattle and drone away, unless you like that sort of thing.
