So check this awesomeness out!! My boy Nick from Forever Two Wheels had this great idea for an exhaust baffle.  You see, up here in Maine we have some pretty ridiculous inspection laws.  We are breaking everyone of them on this build, but excessively loud exhaust will get you a ticket in a heartbeat.  Hopefully this will help.  

So here we have an exhaust tube measured and marked up:[/size]

slots cut:

That is an interesting way to make your own baffle.

If that baffle is going into the megaphone housing, I suggest that about half way down the baffle section you block it off completely in the center so that nothing can flow straight through.  That way the exhaust (and sound) must exit the baffle and go into the megaphone housing, then the exhaust (and sound) will have to go back into the baffle to exit the muffler.

It still is going to be pretty loud.........I betcha!  

I am wondering if maybe those segments should have been pushed in varying amounts, to slow exhaust gases on the outside edge , too,,

Good advice y'all.  Hey Gerry, the backbone measures 13" long and 2 1/2" wide

That is my dream or fantasy bike frame, gas welded bronze intersections and mill finish steel tube, with maybe a satin clear coat over all.
I have a 1972 Triumph Bonneville that is my next project.  I would love to find a Rickman or Seeley frame (original or clone/copy) for a unit twin motor welded like that and put modern forks, alloy rims and brakes on it.
Kind of my own new Norton.
Project is looking good Dfinn,

Things are starting to shape up around here!  We got some exhaust work done today.  First off we had a new collar machined to fit the 2" exhaust.
It couldn't be better! Perfect fit.[/size]

So than we tack welded the first bend and this is what that looks like.[size=20]


We mocked up the exhaust and this is basically how it look.



 Than Nick came up with a new idea for the seat.  Calling on café racer heritage this is what he was thinking.....I agree it looks great!!

Your seat looks great.....but is probably more like a Street Tracker look than a Cafe' look.  Street Trackers have the back of the seat turning up like yours.....Cafe' racers have the dome on the back.....although none of this has to follow any hard fast rules.

I am interested to see the stainless welding......I am really poor at welding stainless with a Mig.  Tig is much better for stainless.  It is hard to use a welder just once or twice a year, and be any good at it.
