STX15f 40$ Exhaust mod
Iím new to the forum but been on here for a few months lurking and reading up on the current info. I did some searching on how to do acheap exhaust modification to my ski. I came up with three different ways but it seems like most of the people who posted the info hardly come on the forums anymore, therefore the questions I had couldnít be answered in a timely fashion.
I chose what I felt would be the easiest way to get rid of the second water box, a Silicone U elbow. I havenít driven it yet but I did run it while flushing it and everything went fine. If anyone wants to know where I got this send me a PM.
If there are any opinions or concerns Iíd like to hear them before I go on the water this weekend.
Here are the specs on the elbow for anyone whoís interested.
Genuine 4-ply Silicone (5 silicone layers plus 4 reinforcement layers = 9 total layers!)
Installer can cut silicone parts down to fit with a razor
Heat tolerance: -40į to 392į Fahrenheit
Burst Pressure: 200 PSI
Working Pressure: 50 PSI
Wall Size: 4 mm - 5 mm

Looks good. I did something similar last fall using a ABS p-trap and the exisitng hose. Some are using an aluminum U tube as well.
Have you removed the second water box yet? I left mine in for a while but finally pulled it out this spring. I was afraid of the jack and cracking my hull but it worked.

Should be no issues with that set-up. Looks good.
Whre did you purchase the silicone tubing from?

Thanks! Yeah right now the second water box is in there. When I have time over the winter I want to pull it out. The pipes from siliconeintakes.com, the 2.5in diameter. I wanted a one and done sort of pipe and I figured 40$ with shipping isn't bad. It goes on easily.
