Re: Johnson motor with exhaust bypass

[wiscoboater]

When you see an exhaust like that, or the long pipes seen on the racing motors used on hydros, are they separated inside the exhaust cover Isolating each cylinder? or is this open inside the exhaust cover both pipes getting exhaust from both cylinders?. I have seen some of these setups for Mercs on feebay and they are always big bucks. I would love to try and make one some cold winter day in my basement shop.
