Well, over the last month, I've been slowly buying (and minimally installing) various bits on the new-to-me 4.6is.
So far I've swapped to Sypder Auto smoked non-LED Tails with LED bulbs (yes, I did this intentionally), LED smoked side-markers, and gloss black kidney grills.
I've purchased, and have in possession, but have not yet installed: Evox-R Bi-Xenon Projectors, Umnitza Opaque Orion V2 Halo Rings, and a Dynavin N6 unit.
I've not yet purchased / received: Sub and Sub-enclosure to replace DSP sub box, and Mono Amp
....and just so it's semi-relevant for a "what did I do today" thread, I fabric taped the Dynavin Fakra Cable so it looks OEM when installed.
