problem was the coil arking out on the negative post of the coil.
i stopped on the side of the road and i could hear it just zapping away. changed the coil and no problemo
google "exhaust backpressure" and have a real good read of it
if you do exhaust you should do a intake mod aswell (carby etc etc) so everything works together and makes more power
its got a 3k in it now? if you want some improvement in power put a 4k in. if you want a POWER HOUSE put a 5k in it.
everything bolts on/ interchangable
I'm pretty sure youll need 2 pairs of ballast resistors to power 4 globes. so youll need 2 kits.
got hid driving lights and normal yellow high beams for the middle
a couple of my mates got hid high and low beam kits and they never use high beams!
you still can use H4 low beam/high beam globes and just wire it to use the high beams only.
edit - just go the pick a part for h4 globes. its only $1 entry :rolls:
