Unleash the true, deep rumble of your heavy V-Twin engine by bolting on the flagship Vance & Hines Oversized 450 Blackout Slip-On Mufflers. Custom-engineered for modern Harley-Davidson Touring platforms, these massive 4.5-inch diameter slip-on exhausts deliver an aggressive acoustic transformation, enhanced exhaust gas scavenge efficiency, and an imposing dark custom look that commands respect on any highway road trip.
Restricted factory mufflers choke your motorcycle's exhaust flow, trapping intense heat inside the cylinders and muting that classic American V-Twin acoustic punch. Vance & Hines eliminates these factory limitations by wrapping a heavy-gauge steel shell around a high-flow mechanical baffle system. The massive 4.5-inch diameter allows room for an advanced, large-displacement internal core that provides plenty of surface area to absorb harsh high-frequency pitch notes. This mechanical design transforms your exhaust flow into a deep, guttural baritone roar that stays smooth at sustained highway cruising speeds without causing annoying inner ear drone, while maintaining the critical exhaust backpressure needed to boost your low-to-mid range torque curves.
Advanced Coating & End Cap Specs:
Unlike standard thin chrome pipes that discolor, bubble, or blue when exposed to the high heat of modern air-cooled engines, these mufflers are shielded in a high-temperature matte black ceramic powder coating. This industrial coating seals the underlying metal structure from road salt, water corrosion, and boot marks. The rear exits are finished off with CNC-machined billet aluminum Blackout end caps featuring subtle, laser-etched Vance & Hines branding details that flow seamlessly into the factory saddlebag contours of your bagger.
Mechanical Specifications & Sizing Geometry:
- Muffler Outer Diameter: Massive 4.5-inch (114mm) oversized structural canister profile.
- Material Base Build: Heavy-gauge cold-rolled steel housing with CNC-machined aluminum end caps.
- Finish Treatment: High-temperature, race-grade matte black ceramic coating.
- Internal Core Design: Large-diameter louvered core mechanical baffles with high-density wrapping.
- Mount Interface Type: Direct bolt-on slip-fit collar utilizing your vehicle's factory exhaust mounting points.
Guaranteed Touring Fitment Validation:
This Vance & Hines 450 Slip-On Exhaust Pair features an optimized hub layout built natively to slide perfectly onto standard factory head pipes or aftermarket dual exhaust configurations. It provides a direct bolt-on performance upgrade for full-size Harley-Davidson Touring models, including: Electra Glide, Ultra Classic, Road King, Street Glide, Road Glide, and corresponding CVO bagger configurations. Please Note: This high-flow exhaust layout is custom-profiled strictly for touring frame baggers and does not fit Softail, Dyna, or Sportster platforms. Please verify your machine's model year range prior to final assembly positioning.
Installation Tip: Mechanical and engine safety is paramount. Thoroughly clean the matte black ceramic surface with a clean cloth and rubbing alcohol before firing up the engine for the first time. Any oils from your fingerprints or grease left on the pipes will permanently bake into the ceramic coating once the metal heats up, creating irreversible blemishes.
