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