I was also able to get the intake, bypass and exhaust pipe ruffed in. I had earlier glued in the aft exhaus pipe support 7/16" from fuse end. I positioned the exhaust pipe to have a 3/16" overhang. When setting up for mountinf the bypass to the exhaust, you want to make sure this exhaust pipe position is kept.
I marked center lines on both end of the bypass and exhaust pipe so when mounting both together, they were straight in alignment. I used a laser line to adjust this. Then with a 1/2" of the bypass inserted into the exhaust pipe, I drilled 2 holes into the lower bypass section to assemble these parts. When trying to assemble the whole bypass into the exhaust opening, they would not fit. I found that there was a lip in the bypass halves that needed to be sanded smooth to get a tighter fit. But I also needed to used a dremel to sand down the 1/2" lip to allow the whole bypass to fit properly into the exhaust tube.
I then assembled the front intakes to check for proper fit to the front of the bypass. After making sure that there is enough overlap to all these parts, I put a couple small screws into bypass motor mount location so that I can keep this all alignment while I setup the front intakes. So, the front intakes will come next time I get back to building.
