Ah these are some hot pics.. i can't go any lower than my current.. front of D10 is already lowered enough, just one finger gap between tire and body.. issue is for the rear.. when i floor the paddle, rear sits down.. atleast by 2,3 inches.. if i drop the rear any further, it'll kill the suspension every time i put my foot down 
Jazak ALLAH mate 
about the drop, answered up there.. about exhaust, its a custom exhaust with the drum from some old AMG exhaust.. it stays silent untill rev'd hard..
If i get a good enough offer, i'd consider the sale.. making another such car, or getting one would be fun.. plus since you got that bike, its been tickling me
lolz. cost to build was above 2m.. my purchase was a little less than that.. a good offer could pursue me towards the sale..
Ah it sure is.. tell you guys what, i'll shortly post the engine bay 
Jazak ALLAH
Ah thats very generous of you.. do try to find it..
