Nice sounds. Wouldn't believe it was a 318. Wish someone would post a 273 Commando with the straight through primary muffler and box end resonator. That son-of-a-gun sounded stout. The straight through was only used on the 65 Commando and Charger 273 motors. 66 & 67 used a low restriction reverse flow muffler which failed to capture the heartbeat of the street. B/RB and LA 340/360 had fully functional duals.
