Stock these Volvos have about 300 bhp. But since this is a Guerrilla demo car we can't settle for only 300 bhp. The car's received a freeflow Guerrilla 3 inch downpipe with a race catalyst and a catback Guerrilla performance exhaust that evolves from 3 inch to 2.5 inch. We chose a sophisticated oval tailtip, fitting perfectly in the rear valance. We expect the car to have a little over 350 bhp.
