So Dirt 3 has a really cool remix of this song but I can't find the Dirt 3 remix anywhere on youtube (or whatever the remix is called). It feels more laid back, fatter synth and beat. It plays during some of the menus.
  
Can't find it anywhere (ie: youtube, itunes, etc.) 
Can anyone else find it?

You won't find anything if you look up "DiRT 3 remix".
 
As far as I remember the song in-game had a DnB remix. It has probably been remixed by some DnB artist, I don't know.
 
I can't seem to find a full list of the game's soundtrack. There are some tracks I like and can't find 'em anywhere also. Guess I'll wait until Codemasters release an OST album with all of 'em inside.

I don't have a link to the song you're looking for @bigmuffpi, but here is soundtrack list you were looking for, @antikorper.

wow i'm a dumbass never mind

I prefer the 90's original, and Ray Keith & Nookie's version from '93 
 
Absolute hardcore fucking classic - Oi Oi! 
 
  

God this just reminds me how F'ing GREAT the music in this game is. Time to go search for another great videogame soundtrack.

My favourite track in the game by far!  When it plays I just scroll through the menus for a while.
 
One thing that really bothers me with the Dirt games is the lack of control over the music tracks - no options for deactivating songs completely, no skipping etc.

@Contro: Fuck yeah, man!  Browsing YouTube for 90's hardcore classics is where it's at!  Might I recommend "Feel Real Good" by Manix, if you haven't heard it before.  I'm usually not one to just recommend random singles, but man, this one deserves it.
