the snakes help heaps ! trust me ! my old rb25de had a set of killer genie snakes on her, a quality simota air filter on it & a turbo muffler and the turbo boys used to have no chance !
my mates dad had a r33gtst that was boosted to 2 bar and over the first like 300 metres i had him cold !
for the measy outlay of $739 fitted, it really gives you a kick in the pants as opposed to one with standard exhaust.
Gotta fly guys, got turbo butts to kick !
