i was in the process of putting a "f" exhaust on my "k" and gave up after finding a free 4-2.... but everyone is right about the brake pedal and mounting bracket.... but you'll also need to switch from the spigot mounts currently on your k, to studs found on the "f". not all that hard, but if your trying to do it on the cheap, all the extra little #$%* can add up!
