Happy for you and know the excitement and anxiety of waiting for a new truck to arrive. I would like to say though, as someone who also just got a new 2021 Ram with the 3.92 axle, really think about your muffler (or delete) decision. The 3.92 axle means that at highway cruising speeds (around 104km/hr to 115km/hr) you'll be in 8th gear and around 1800-2000 rpm, and at that speed and rpm's your exhaust is going to drone like crazy, and it will be pretty unbearable in no time. I put on a Flowmaster Super 44 and at highway speed/those revs it was really bad, so I cannot imagine how much worse a straight pipe and deleted resonators would sound. Forget about listening to the stereo, or hearing a phone call through bluetooth, or having a conversation with any passengers in the truck, you won't be able to think let alone hear those things.
I ended up with a Flowmaster 50HD and it is MUCH better now, hardly any drone, and if there is it's bearable, and you can still hear the stereo or passengers etc.
I know it's a personal preference and to each their own but, I would honestly think twice about straight pipes and deleting resonators. If you drive highway a lot or have people in the truck, you'll regret deleting them all I feel.
Either way though, congrats on the new truck, post pics, would love see it. I've had black vehicles about 4-5 times now and won't ever again, again just personal preference and experience. They look amazing when washed and cleaned up but 5 mins later I see the dust or dirt and it drove me crazy, being a neat freak lol. This time around I got a 2021 Classic in Granite Crystal Metallic, still on the darker end of paint shades, but not quite as bad showing dirt and dust.
