It was a little under $200 I believe and it's a direct bolt in (no shaving, grinding, or cutting anything. I ran it as a one-wire unit w/ a 4 gauge wire and a 130amp circuit breaker, which was around $30. Total, it was under $250, so you could save $50 and have. My particular one was tested at the factory to put out 95 amps at 2400 Dyno rpm and 143 amps at 6000 Dyno rpm.
