Typically the progression is something like this (everyone has their version of "the list" of course

)
- catch can, CAI
- some then go sequential tail lights....
- exhaust (reso deletes - be careful on auto as their is DRONE moreso than on 6 speeds, muffler replacements, catbacks, and eventually shorty headers (or LTs - but only if you are adding more power mods, otherwise you will get better lower end torque with the shorties - and the shorties dont throw codes like LTs do))
- lighting and exterior bling - sooooo much to cover, thats probably its own thread
- wheels and tires, brake upgrades
- engine bay bling (half covers, billet accesories, hood scoops (shakers or T/As), coil pack covers, hoses, custom reservoirs, etc,
- suspension mods - lowering kits, tower braces (front and rear), rear ends, drag radials, etc.
- engine mods - tuners, cam, heads, fuel system, nitrous or superchargers or turbos
By this point you are a much poorer (but no doubt happier) Challenger owner !
