Cobra Triovals
Having a set put on an '07 Road King this week. HD 103" kit, Forged H-D SE pistons, 255 cam, Thundermax Auto-tuner, stock header pipes, K&N filter, Amsoil all around. Should be dynoed either tomorrow or the next day. Slip-ons were the only change so I will able to tell what kind of Torque or HP gains, if any, the mufflers alone give.
