So I'm really over the whole "loud exhaust" thing now on our 1984 5.7L Alpha One. I'd really like to convert to through the prop exhaust. I'm sure my fellow boaters would appreciate it as well. But I really don't want to pull the engine to install the Y pipe. I was wondering if it could be done with some flexible exhaust hose and connectors or something that would allow me to make the conversion without pulling the engine out. Any thoughts?
