I'd recommend removing the easy sellers: Code3, NW CAI, and maybe the shorty headers. Those will all sell quick and for decent money. The rest probably isn't worth pulling off.

I learned when selling my VW a few months ago, people want it to appear close to stock. My body kit killed me getting a decent offer. I pulled my race axles and got a whopping $50/ea shipped for them (paid $200/ea). I couldn't even sell my race exhaust, I ended up throwing it away. So, I'd say the same would go for the SRT's used suspension and exhaust parts... people won't pay much for them and they are heavy to ship.
