I have a 1987 js440 it has a straight 15 impeller with kerker short body pipe running 150 compression.
My question is has anybody put a half pipe on a 440? How did it work? Do you think there would be any bottom end gains from running a factory halfpipe on the 440 as opposed to the kerker short body. I have one to use and put on it so i was just wondering if anyone had done this and what happened. Any info would be appreciated.
