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, our new pipe has its sections welded together to maintain a wide Φ60.5 diameter throughout with additional weld beads on the inside for rigidity.

Even with the stock setup, handling around the joint pipe pass-through is challenging given the limited clearance. However, our dedicated engineers have achieved precision clearance even with the wider pipe.
