Twisted Choppers Bearing Support Slash Cut Exhaust Header For 1986-2022 Harley-Davidson Sportster

The Bearing Support Slash Cut delivers the clean, angled tip profile of a 2-into-2 header engineered specifically to clear and sit just in front of an outboard bearing support, giving wide-tired custom Sportster builders a purposeful exhaust solution that fits the way their bike was built to look.
