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