Each header package includes the IAG 60mm uppipe that utilizes a 3-bolt cast flange and multi-layer gasket between the manifold and uppipe, providing a stable connection without exhaust leaks. The IAG Header & Uppipe adds all of the hardware and high quality, multi-layer gaskets needed for installation including specialty copper exhaust nuts, which are proven to maintain their torque even in the extreme conditions of heat cycling present at the exhaust flange.
Due to the equal length design, these headers will alter the exhaust tone from the distinct "boxer rumble" to a smoother exhaust note.
