i have a similar set up to tracker8wr except i used exhaust flex pipe. 2-1/4 and i bashed my hood a little to fit it. dont have a fitting on it i just run it straight back, i havent tested it for complete suction, im sure pvc would work better, but its better than stock. it i stick hold my hand over it, it sucks really hard so i know it works better than no snorkel. just remember if you are traversing deep water, anything you have is better than nothing and blowing a hole in your motor.
