I know your skeptical about taking the bumper off. I was too, but its soooo easy when you follow Ak370z's diy + Digitoniums bumper removal. I did it by myself in 3 hours and half the time I was drinking beer. Trust me... the butt dyno says its worth it! As for cutting the holes, effing simple. I did mine w/ a drill!
