Wow awesome sound, have you take it out for a road test yet. 
Just got it on the road today, and holy crap does it go.
Took it for a drive up the hume and floored it where the speed changes from 100 to 110,
it threw me back and i was well over the limit within secs.
I definatly need to change diff center tho, it didnt like sitting below 80Km's
Looks like i need to go to a 3.25 or 3.5 like glenn70 sugested in a diff post
