dunno if its a supercar, or was, but just spotted an old school maserati mexico in surrey hills.
i wish v8's sounded like that nowadays. see below, but was purple.
on my old r32 gtst i had:
custom 3" turbo back exhaust w/hiflow cat
Dr.Drift remap, not a good tune, but good enuff
040 pump
GKtech fmic
manual boost controller @ 14psi
stock airbox
with that i made 169.2rwkw
