Any suggestions on the best way to black out the grill? I'm not a big fan of chrome look.

if there is not an OEM option.... plastidip it or wait for an aftermarket option to black it out

1st mod, tint to match back windows.

...edit, sorry overlooked the GM request

Installed the K&N CAI, the JLT 3.0 catch can.
Also attempted to install LED brake, turn signal, and reverse lights. Even though i bought the ones with build in resistors I've been getting brake and reverse light errors.

Checked my catch can only after 4 days and 200 miles of driving, not expecting to find much of anything. To my surprise there was quite a bit of oil in there for how little time it was installed. I'd guess about 3-4ml of oil. Much better to have it caught in the can than to get sucked into the intake!

5 minute mod today, wired my exhaust valve open trying to get a little more noise out of the stock exhaust. Made a difference at low rpms accelerating from a stop. No drone at highway speeds that i've noticed.

You wired it open? Doesn't it protest when it tries to close? Will this damage anything long term since its unable to do what it wants to?

Waiting for GM to allow the Air Suspension option on the Denali. Dealer says its gonna be available to order beginning 9/7!
