I had posted a question earlier regarding replacement muffler. I have removed old one and the inlet/outlet size is 1.5 inches, smaller than anything I have been able to find to replace.
Given the engine is raw water cooled, how much noise dampening effect does a muffler provide? I am wondering if I ought to "straight pipe (hose)" from exhaust/mixing elbow directly to exhaust port. Is this an idiotic thought?
