Description

EC Steel Exhaust Flange for Predator 670 V-Twin – Custom Header Fabrication


Build your own custom exhaust system with the EC Steel Exhaust Flange for the Predator 670 V-Twin Engine. Precision cut from high-quality steel, this flange is the perfect starting point for fabricating headers for performance applications like racing lawnmowers, pulling tractors, mud boats, mini trucks, and modified golf carts.


With a 1-1/4" inside diameter, it’s designed to match the exhaust port on the Predator 670 and 1-1/4" exhaust pipes, giving you a strong and leak-free connection for your custom setup.


Key Features:

  • Fitment: Designed for Predator 670 V-Twin engines
  • Flange ID: 1-1/4" (matches standard 1.25" OD exhaust pipes)
  • Material: Durable mild steel—ideal for welding
  • Sold individually – order two for a complete set
  • Great for performance builds using custom headers

Whether you're upgrading for more power, better flow, or a unique setup, this exhaust flange gives you the solid foundation needed to start your custom exhaust build the right way.

FAQ

Q1: Will this exhaust flange fit other V-Twin engines besides the Predator 670?
A: This flange is precision-cut to match the port spacing and bolt pattern of the Predator 670 V-Twin. It may not fit other brands like Vanguard or Kohler V-Twins without modification.


Q2: What size exhaust tubing should I use with this flange?
A: The flange has a 1-1/4” inside diameter, which pairs best with 1-1/4” OD exhaust tubing. You may use reducers or adapters if you're running a different size header pipe.


Q3: Can I weld this flange with a MIG or TIG welder?
A: Yes. The flange is made from high-quality mild steel, which is ideal for MIG or TIG welding during exhaust fabrication.


Q4: Is this flange sold as a pair or individually?
A: Each flange is sold individually. If you're building a full exhaust system for both cylinders of the Predator 670, you’ll need to purchase two flanges.


Q5: Do I need gaskets with this flange?
A: While not included, we recommend using Predator 670 exhaust gaskets or high-temp RTV sealant for a leak-free seal between the flange and cylinder head.


Q6: What vehicles or builds is this part commonly used for?
A: This flange is ideal for:

  • Racing lawnmowers
  • Pulling tractors
  • Mud boats
  • Golf carts
  • Off-road go-karts and minibikes using the Predator 670
