107 Coil – Handmade 2‑1 Custom Exhaust for Milwaukee‑8 Softail

$1,150.00

The 107 Coil is a distinctive 2‑1 custom exhaust system crafted specifically for Milwaukee‑8 Softail models. Each unit is meticulously TIG‑welded from 304-grade stainless steel in our Houston shop, delivering unparalleled fit and finish. The 107 Coil inherits the modular craftsmanship and performance-first approach of Softail exhausts by Kinetic, including integrated flanges that simplify bolt-on installation.

This system comes with factory-compatible foot controls, handles EFI models, and features internal ceramic coating to reduce external surface temperature. Whether you're building a custom café bobber or upgrading your stock Softail, the 107 Coil delivers refined aesthetics, performance tuning potential, and passenger-friendly tip options.

Specifications:

  • Made from 304-grade stainless steel, fully TIG-welded

  • Includes integrated stainless flanges and O₂ sensor bungs

  • Internally ceramic-coated for improved heat management

  • Engineered to work with all stock foot controls (pegs and floorboards)

  • Modular design allows tip swapping—select style at checkout

  • Handmade to order with approximate 4–6 week production time

Important:

Passenger comfort depends on tip design. For two-up riders, a 45° or 90° angle slip-fit tip is recommended to redirect exhaust away from passenger positioning.
