S&S Cycle 1999+ BT 4in Bore O-Ring Exhaust Gasket Kit

If you're working on the exhaust system of your 1999 and newer Big Twin motorcycle, a good gasket is crucial for a leak-free seal. This 4-inch bore O-ring exhaust gasket kit from S&S Cycle is designed to provide that reliable connection between your exhaust components.

This kit uses O-ring style gaskets, which create a tight seal by compressing into the space between the exhaust pipe and the cylinder head or collector. This design helps prevent exhaust leaks, which can lead to lost power, poor fuel economy, and an annoying exhaust note. The 4-inch bore size is specific to certain Big Twin applications, ensuring a proper fit for the intended motorcycles.

Keep in mind that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation to ensure the best performance and longevity of your exhaust system.
