You can look on the Cadillac app you receive when you purchase your 21. Alot od accessories on there. I had a dealer install the performance exhaust on mine to no avail though, not compatible so I assume they’re still putting finishing touches on everything. I did get the monochromatic emblems, license plate frames, cargo light up logo on the app. Very sharp. I am actually looking to do a suprr charger on mine and the brembo brakes if anyone hears any info on those items. I can’t locate anywhere just yet.
