If your talking about the engine intake, I can't help you, because I haven't gotten there yet.
If your snorkeling the clutch case, then there are some things you've got to keep in mind.
1) the clutch creates a lot of heat. No matter what set up you use, you will be making this worse, and that has an affect on the life of your belt.
2) there is no way to snorkel the exhaust side and keep it at the original 3", you have to reduce it to 2", which reduces the air flow through the system.
3) The more bends and the tighter they are, the more you reduce the air flow.
That being said, the stock system is garbage and poorly designed. There's little option for me and where I ride. I had to snorkel mine.
My intake I ran straight from the clutch, along side the drive shaft, under the hood. That way I didn't have to put any 180 degree bends in the line, (such as when you put it behind the seats). I had to put a shroud around it though, because of the splashes from the front tires. Works really well. I never get a wet belt anymore.
The exhaust side, I used a 3" to 2" Rubber fitting. I put it into boiling water before I put it onto the clutch case, (made it really easy). Then I used a 45 degree elbow and ran it up behind the passenger seat. I only made it a foot long.
Only issue with my set up is the heat build up. The back of the passenger seat gets quite hot. The exhaust line gets so hot that it melts the black (ABS) plumbing pipe I used. When it melts, it shrinks and the hose clamp lets go. The water gets in the exhaust side. I need to make the exhaust line out of steel some how.
Some guys will tell you that you are stupid to snorkel the Teryx, because there are already heat issues with the stock set up, and the Teryx is known to have belt issues. But I simply had no choice. My riding area is far to wet, and everybody I ride with has quads, so they can go anywhere. So far, I've had no belt problems.... It's been about 500 miles since I did my ride.
There are several threads on this topic at the other site. Might be here too, but I haven't checked.
