VANCE & HINES - 3" Twin Slash PCX Slip-Ons - Softail 10-17 Chrome or Black

Installing a pair of Slip-On mufflers is one of the best options to start customizing your machine. Specially developed for the Harley-Davidson Softail (2010-2017) with Twin Cam engine, the Twin Slash PCX 3" mufflers provide the iconic slash-cut look of the American brand while unleashing the performance potential and character of your V-Twin.

PCX™ Technology: More Torque, Less Heat

This generation incorporates patented PCX™ (Power Chamber Exhaust) technology. Underneath its heat shields, it houses a high-flow catalytic cartridge with dual-matrix chambers. Ideally positioned downstream of the flow, this internal architecture optimizes back pressure to deliver:

• More Dynamic Pick-Up: A significant increase in mid-range torque for sharper and more responsive accelerations with each gear change.

• Unparalleled Thermal Comfort: A drastic reduction in heat radiation, showing up to 20% less heat at the footpegs or floorboards and up to 50% less heat accumulated at the manifold.

• A Unique Roar: A refined acoustic signature, unleashing a deep, heavy, and raw rumble, without compromising the clean aesthetic of the line.

"Blue-Proof" Anti-Discoloration Design

To ensure a perfect and durable aesthetic, the 2-1/2" (6.35 cm) muffler bodies are completely covered by 3" (7.62 cm) diameter heat shields. Virtually invisible, these thermal shields insulate the inner steel from extreme temperature variations, thus eliminating any risk of visible bluing or yellowing.
