ive used a few over the years but have reverted back to using twins, as most want to drive in traffic traffic.
The ORC twins drive like stock and have a light pedal but the tripples are too agressive for a daily in peak hour traffic IMO. I lived with one in a supra for a year before i retrofitted a twin and never looked back, car was only making mid 400's though so it was not really stressing the twin.
what sort of power you making?
