The locking fasteners are designed to replace factory header bolts directly, fitting perfectly with OEM header flanges on the specified vehicles. No modifications to the exhaust system or engine components are necessary. Proper installation following Stage 8’s instructions ensures optimal locking performance and ease of future removal for maintenance or upgrades.
