The COBRA 4" NH Slip-On Long is engineered for NH Softail models, offering a distinct visual and sonic profile that mirrors the original equipment. Constructed with a 4-inch round body available in Chrome or Black, the exhaust features a 4-inch billet aluminum outer tip with distinctive machined dual grooves, while the chrome variant utilizes a matching chromed inner tip. The extended length reaches just past the rear disc and nearly to the rear rim, providing a substantial presence. Inside, the system employs 2.25-inch louvered cores developed by the Cobra team to deliver a deeper rumble while maintaining strong sonic similarity to the original NH design.
Performance is optimized for the stock 2-into-1 Softail head pipe, ensuring robust power delivery from the factory configuration. The core design is built to accommodate future upgrades, generating increased performance when paired with larger engines or standard industry hop-up parts. This 50-state legal exhaust is manufactured in the U.S.A. and is specifically designed for NH Softails, with explicit incompatibility noted for Breakout and Fat Boy models.
