welded up Y... as you guys that have done fab work in the past know... there is so much trial and error...
the Y is not pretty but it is so soild... no leaks and it will clean up well...
notice the pipe is tied into the Y pipe bolt... the pipe moves with the Engine...
also you can see in this pic (1) and (2) that we sectioned the pipe (expansion chamber) and turned it many times in different directions.. should the pipe come out the stock side or the other...
should we run it down or up... the pipes shape and length remain unchanged except for the Y... we just massaged the direction some

after reading about other builds... Hoser's 440 install comes strongly to mind I wanted to keep this a bolt in
Engine and we used the stock mounts... the sled's stock mounts are used and we tied into them... the stock mounts are rubber mounted at four points and this will dampen vibs a bit... the stock sled mounts are this thin, cheap,
SH*t metal and the mounts we made are way over kill....LOL
The Pilot Engine was tied tight to the trans as far as we could see and we did the same..
The sled Engine moves with the trans completely.... we will only learn our mistakes after it is up and moving...
as noted above the pipe is tied into the Y pipe/Engine... the Engine has slots in the mounts
in case we need to adjust it (I am sure we will need to fine tune it) and the Pipe being mounted to the Engine will allow this... the rest of the pipe (silencer) will be mounted via pull spring

we had to change the cage some... the cross bar that held the elec. and the top harness bolts was/would have come into contact with the head if it was left stock...
the center portion was cut out first and then we cut the shorter supports...
we then moved the whole unit up after down sizing the center section that we first removed... the cage as everyone knows tappers in at the top and just a cut and hike would not work...

the rear of the Engine... the carbs are up over the trans and notice the relation of the seat with the Engine... a seat tie in to be added for seat back support... oh and yea there will be a much needed piece of aluminum to keep me from having hot cross buns... the stock carbs are gone and I have TM 38s MM on order with button choke.. one less thing to tie into the front of kart... ie choke cable...
