RE: Header and Tuned Pipe for OS 21 XM Outboard
James - re your last post in reply to my search for a header/tuned pipe for my OS 21 XM Outboard. For the life of me, I can't picture how the parts come together on the engine. It seems to me the header pipe points downwards and the exhaust points sideways ... is that right? Or does the header come out sideways and the pipe turns it 180 degrees sideways in the other direction? Isn't there anything that comes straight out? Seems like a lot of 90 degree turns to me.
