Common questions
Can this exhaust donut be cut and re-angled?
Yes, this mandrel-bent tube is specifically designed to be cut and shaped to fit your custom exhaust layout, allowing for precise angling and routing.
What does "mandrel-bent" mean for an exhaust component?
Mandrel bending uses an internal support to prevent the tube from wrinkling or crimping during the bending process. This maintains a consistent diameter and smooth flow path, which is crucial for exhaust performance.
Will this fit any V-twin motorcycle?
This exhaust donut is a blank tube designed for custom fabrication on V-twin motorcycles, including Harley-Davidson and Indian models. It's meant to be integrated into a custom exhaust system, not a direct bolt-on replacement.
