fourtrak exhaust

right so reading up on parrots build im debating about making up a new exhaust flange with screamer pipe to enter the exhaust at a later point but also to upgrade the exhaust...larger bore. however the quick question is what size do i go to and what size was the screamer pipe? also will i run into issues wading with a larger bore exhaust because wont it carry less pressure to keep the water out? or am i being silly? cheers for any help Very Happy

don't worry about the wading issue it definitely wont make a difference, just don't stall!
no idea about screamer pipe though, I didn't bother with anything like that just upped size to 2.5inch and left it, its not like they're high revving massive power engines! Wink

Mine works well enough.... Smile
