Engineered for Harley-Davidson FLH and FLT models from 1995 to 2016, these Cobra 4-inch NH slip-on mufflers feature a classic, aggressive aesthetic defined by round 4-inch bodies that bell out to 4.5 inches at the rear. The design is completed with a rolled tip fin for a clean, finished appearance, while the internal architecture includes an 8-inch spun and louvered baffle. This specific internal configuration, capped by a trumpet-shaped inner tip that harmonizes with the belled end, produces the distinct NH sound characteristic of the line.
Constructed in the USA, these exhaust components are 50-state legal and backed by a limited lifetime warranty. The combination of the precise bell-out geometry and the specialized baffle system ensures a consistent acoustic profile suitable for both street and track environments. As a hard part designed for the 1995–2016 FLH/FLT platforms, the unit delivers a refined visual upgrade alongside the signature performance tone associated with Cobra exhaust systems.
