right to the manifold and drops a few inches to the cetec muffler. It comes out of the muffler and goes high up to a vented loop and drops down into a resonator. From the bottom of the resonator it parallels the waterline and exits the stern. The only water the muffler holds is the short hose from it to the vented loop. If you can get your mufflers a foot below the injection elbow you would be fine with no weight on your manifold.
