Anyone order/have the Performance Upgrade Package on a 21?

Looking to get in line for a '22 Denali and saw the "Performance Upgrade Package" listed. Anyone have it? Feedback on it? Any thoughts if it is California legal?

What I find especially interesting is the picture on the description of the package looks to have a cold air filter... which are usually hard to get past emissions in CA... unless they are one that is tested by the govt. regulators. Its a bit pricy... but if it makes a big difference/sounds cool/doesn't kill my gas mileage (which is knowingly already going to be bad)... then i'm interested.

It was on back order when I picked up my 21 Denali. Just got it installed a week ago. Didn’t notice much difference performance wise. Exhaust is not abnoxiously loud but has more drone inside the cab. In conclusion, I’d save my $ and buy a corsa exhaust when it comes out.

It’s all about noise. If that stuff worked to improve performance they’d be banging a drum about it.
