Put the coupler on the headpipe and chamber, lock it down, and youll still have a bit of room to adjust the chamber up and down.

Is the pipe hitting the wall where it was reinforced. We've seen that problem where the reinforcement causes the pipe to rub on the sidewall and cause alignment issues

Yes it is 3 or 4 inches from the head pipe. I sanded some of that area to the point I was into the smc and also knocked a little off the weld on the pipe. Minimal gains

Can you rotate the pipe slightly? The end is cut on an angle if I remember correctly and that would raise the outlet.

Theres very little rotation but where it's sitting is where it wants to be. Joint at head pipe is perfect and it's sitting at the same 6 3/8 As my buddies on the stinger side. Hes running a x metal. I'm done looking for solutions, a new box or modify this one are the only options

Looks like you might have too much pad under the waterbox. I have a bunch of rocker on my sj and i used a thin piece of turf under the box but still had to raise one side of the box or the other to get it lined up.
Have you even tried installing couplers from the headpipe to the exhaust outlet step-by-step or did you give up when it didnt seem like it would work when you put the parts there...
the h2o box is an awesome upgrade over the stock rn box. It raises the chamber up slightly therefore creating more gap between the bedplate n chamber. Less likely to crack a chamber into the stock bedplate. Some have got into the habit of grinding the bedplates to avoid issue.

Tried multiple times in different ways. The 2 inch elevation is too much to make up with a 2 inch coupler. Got a 3 inch on its way.
I like to install the bpipe coupler and 45 to waterbox and long exhaust hose all the same time, but leave all clamps very loose and no straps on the waterbox. Then you can adjust the angles and fit of everything before tightening. This helps alot on a/m hulls with lots of a/m parts.

Are u using the proper chamber to box coupler??
Also your hull doesn't look oem Yamaha...either someone is killer at reinforcement or it's a composite hull...the nubs where the strap hooks bolt to look like they are carbon Kevlar and part of the hull...I see the carbon reinforcement on top of that. Could be a lightweight Superjet? And possible it has some built in rocker your not aware of...post more pics if you can

I'm using a 45 degree.
I was using a 45 degree.. I did notice the water box is hitting the front exhaust outlet (plugged). If I could push the box further back I might could get some 2 inch to make the bend.
As for the hull it was said to be built by the ski clinic. From what I can tell its a glass hull reiforced with carbon Kevlar. Somebody got a hold of it and tried some repairs that didn't take so I ripped it out and laid the carbon. Theres no rocker but maybe it's built up some on the inside of the nose.
Yesterday I discovered a crack on the bottom so she's upside down now and going to lay a layer of 1708 and a layer of 3oz carbon down the middle. It was also marketed as a lightweight lenzi but who knows

While you are in there laying glass why not rip out the plugged front exhaust and glass it over.
Not bondo, likely cabisol (sp) i think its a filler compound people put in the bondline when reinforcing. Ive never used it, but seen plenty of skis with it. Then the bpipe hits the reinforcment bc its out so far....
