The COBRA 4" NH Slip-On Short is engineered for NH Softail models, offering a larger 4-inch round body available in either Chromed or Black finishes. The design features a 4-inch billet aluminum outer tip with distinctive machined dual grooves, while the chrome variant incorporates a matching chromed inner tip. These inner tips replicate the original NH form to ensure a strong visual resemblance and sonic similarity to the factory exhaust. The extended length of the muffler reaches just past the rear disc brake and nearly to the rear rim, providing a substantial presence on the bike.
Performance is driven by 2.25-inch louvered cores developed by the Cobra team to deliver a deeper rumble while maintaining optimal power output on the stock 2-into-1 Softail head pipe. This core design is built to handle increased performance demands if the rider upgrades to a larger engine or installs standard industry hop-up parts. The system is 50-state legal and manufactured in the U.S.A., though it is not compatible with Breakout or Fat Boy models.
