The car made 467whp on the mustang Dyno...
The only mods it has i think is a intake and exhaust ....
Also this is the 500hp V10 M5...you should've heard it ..
I wouldve been there to see if I got to install the budget header in time but was too busy. I beat the crap out of my Boss's M5 before. Its a freaking nice ride but kinda annoying when you have to drop 3 gears w/ the SMG. I wouldve prefered the 6 speed.
