The Cobra 6303RB 909 Twin slip-on mufflers deliver an exceptional blend of performance, sound, and style for Harley-Davidson Tri-Glide motorcycles. These 4-inch black mufflers feature a distinctive rolled scalloped tip design that sets them apart from basic slash-cut exhausts, providing a refined appearance and deep, traditional Harley rumble.

• Clean, seamless finish with no visible external screws or fasteners

The constant velocity design optimizes exhaust gas flow while the 2.25-inch perforated core produces the recognizable deep tone that Harley riders demand. The rolled and scalloped end caps provide both visual appeal and functional benefits, with the inner scalloped tip working as part of the tuned exhaust system. These mufflers offer an excellent upgrade for riders seeking improved sound and performance without sacrificing the classic Harley character.
