Upgrade the sound, styling, and performance of your compatible Harley-Davidson Softail with the Cobra 6542 NH Softail Long Slip-On Muffler. This 4-inch round muffler features a polished chrome body, a black billet aluminum outer tip, and distinctive machined dual grooves for a clean custom appearance. The chrome inner tip echoes the original NH design, creating a strong visual resemblance while maintaining a similar sonic character.
The extended muffler body reaches just beyond the rear brake disc and nearly to the rear rim for a balanced, finished look. Inside, a 2.25-inch louvered core delivers a deeper rumble and responsive performance while working with the stock 2-into-1 Softail head pipe. The core design also supports additional performance upgrades, making this slip-on a practical choice for riders who later add a larger engine or other standard performance components. This Cobra muffler is 50-state legal and made in the U.S.A.
