Twisted Choppers Chrome Exhaust Flange Kit For Harley-Davidson Evolution Twin Cam M8
The Twisted Choppers Chrome Exhaust Flange Kit is specifically engineered to solve the common clearance issues found with bulky factory hardware. Featuring a significantly slimmer profile than stock flanges, this kit allows for a much easier installation on single-piece 2-into-1 exhaust systems where space around the exhaust port is limited. This comprehensive kit provides everything needed to secure your headers with a professional, show-quality finish.
Each kit is manufactured for long-lasting durability and a leak-free seal. The package includes high-luster chrome flanges, heavy-duty C-clip retaining rings, and tapered exhaust gaskets designed to crush for a perfect fit. To ensure the hardware stays secure under high heat and vibration, we have included zinc-plated serrated flange nuts that bite into the flange for a locked-down connection. This is an essential upgrade for any exhaust swap on for Harley-Davidson motorcycles.
