I have a 1994 Yamaha Waverunner 3 . Is there much of a power advantage in removing muffler and running a straight pipe for the exhaust? Also, any chance of sucking in water and damaging engine? Thanks

Don't do it..........

Removing the waterbox at most would be 2-3 hp. The power comes from the first pipe (expansion chamber) so if you want more power replace that but I don't think they make them anymore.

Wont give you any advantage at all. Just be annoying to ride and for everyone around you.
