Hey man, congrads on the "hand me down," and welcome to colorado, hope ya like it here... if ya need directions... just let me know. Whereabouts in CO are ya?
As for mods, are you refering more to performance, or apperance? Performance wise, the TRD
exhaust would be good a good buy, and if you're looking at Intakes
I'd definately go for the K&N typhoon line. These two would give you some good up top power, without much low end loss.
Appearance... all depends on your taste. Hope I could help.
