Tomei, Joint Pipe (Over pipe)
Larger diameter for improved exhaust efficiency and precision clearance design.
The stock joint pipe (aka. over pipe) is not only narrow, it also has flattened sections which severely limits the performance gains from fitting a high efficiency manifold. However, our new pipe has its sections welded together to maintain a wide 60.5mm diameter throughout with additional weld beads on the inside for rigidity.
