The motor has been modified to put out 722 horsepower with a new pulley, tune, exhaust, headers, intake, and high flow cats. The gains are not supported by any dyno or performance figures. Really, this is just a bolt on SLR with flat black paint and some interior mods. We could do without the huge 722 graphics.
