Might try a water pump bypass hose from a chevy truck or look at Stainless Marine hose it is a fairly tight 90 deg bend.
My O'Rileys lets me hose shop in the back isles as long as it takes. Looks a lot better but you need to resolve those short hoses.

move the pickup form the manifold from the the front to the back and run a longer hose that loops? wont look as clean but wont have the kink in the hose.

it looks like you could cut some hose length off the bottom side should make it better

In terms of the rubber hose...instead of using a straight fitting on the riser/tail, maybe use a 45* fitting.

The connection you are trying to manufacture out of straight hose is supposed to be a molded hose. The straight hose will eventually get warm and kink. When it kinks you lose water flow and will burn up the exhaust.

EMI shows the U shaped connector hose in their installation guide. Looks like the fitting on the manifold may be a 45 with riser being straight.

I am actually trying to use the u shaped hose from emi . They are going to try and send me a 45 to use on the riser but I am thinking that then I will only have 1" space between the riser nipple and the manifold nipple . May present a different issue. We will see .

And those intstructions you a referring to are for a different riser than what I am now using.

The riser you have in latest pics is a better fit. My rise on rear motors is 6” and front is 9”. Height was needed to prevent reversion. I wanted to be sure when coming off throttles hard, the water in exhaust Can’t flow backwards. Made sure it wouldn’t run up hill. Plus my cams were borderline for wet exhaust.

Be happy with fit and function on the hose and fittings that you are working on. It is critical to not restrict the flow.
