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. |

| OTHER FEATURES |
|
|
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. |
