Glad to read this, I am a bit of an audiophile with a very serious home theatre setup (think racks of gear), plus an audiophile 2-channel stereo setup (Devialet), and also come from an IASCA car audio background, with winning audiophile car systems (think studio Rane EQ's and horns under the dash with JL Audio subs). So my expectations are usually quite high and I drive my systems usually hard.
Having said that, while the 2LT/3LT has a superior system, and I will crank it, I am also looking forward to hearing that 6.2L and NPP exhaust too. Not going to lie though, have been thinking about where I could squeeze a small 8" JL Audio sub, without it sounding too cringy with a frunk rattling, just for a bit of true low end. There is a company in the US that usually make custom fibreglass boxes fit into the smallest of OEM corners, will wait to see what they come up with, but not much room in the cabin to start with, so will appreciate the sound you just did and enjoy the best of both worlds (OEM better system and exhaust/engine sound).
