I would check out Robertsons torque tubes for the exhaust any of the GX390 pipes will fit this motor and they have pipes for boats.

For the intake get this kit everything you need and make sure you get the choke holder it's only $2 and you will want it. I would also buy an outerwear pre-filter nr racing might have them if not "affordable go karts" has them and they a filter for the breather hose that the new filter will not use.
