HMF Utility will give you the power. You will have to rejet your carb with just about any exhaust. Add a K&N or other aftermarket high flow filter too, and snorkel.

What exactly will the snorkel do, performance wise?

[MuddnMason]

More air + more fuel = power. If you do mud/water riding at any depth close to the stock snorkel you need the added protection of a snorkel

[FLIPSTICK]

Not all snorkels increase performance , must have too many angles to increase airflow & most decrease airflow slightly

[MuddnMason]

I have heard that before there Flip. How is that? Given 1.5" inner diameter pipe, same as stock, and given a couple of bends and added length, how in the world can a snorkel, which is out in the open provide LESS air flow than the stocker, which is hidden behind plastic and the gas tank? (geez what a run on and on sentence.)

It's not a simple answer MM, but for an example, have a look at your favorite stream or small brook. Find a good spot where you can see little eddies (mini-whirlpools), or where you can see a standing wave at a rock, or better yet, both.

Study it for a bit.......

It's all open. The water can easily head straight on down the stream. But it doesn't. At the standing wave by the rock, instead of just moving on past a submerged rock, the whole stream lifts. Think about how much water goes over that rock in the course of a minute, hour, or day. All that water continued to rise, even though it didn't have to, and wouldn't have had it been stationary. Now look at different rocks of a similar size. You'll see that in different areas, where the water is slightly faster or slightly slower, the reaction is very different to a similar obstacle.
When the air comes through your snorkle, and hits the first corner, it causes a standing wave as the air ricochets off the far side of the corner. As you drive at different throttle settings and engine RPMs, the standing wave changes a good deal.

Now look at the eddies in the stream. Some of that water is flowing upstream, into the current. You wouldn't think at first that that is logical, but there it is. If you look more, you'll see the situation that causes it. As the water spreads from a restriction (a boulder along the shoreline, part way in the water maybe?) and portions slow to fill the added area, yet inertia carries rest of the water at a higher speed, it causes the swirling pattern.

As the air enters your snorkle, it goes from being free to careening down this relatively narrow tube. Friction against the side of the tube slows the outside most layer of air, but not the middle, causing a "swirl", or an eddie that (except where it is interrupted by other turbulance) goes the length of the pipe. (BTW, that's why nearly any factory snorkle has either a funnel shape (cars) or an entrance that is smaller than the rest of the tube). Now you come to the first corner. But the air doesn't know it's a corner until it hits the far side, so when the first of the air that you're imagining flows into the elbow, before it's forced to turn, there is a space that opens up to it's side, like when the stream widens, an eddie will form on the "Inside fo the turn" on the engine side of the elbow. Now there's kind of a small space for air that's still 'flowing" to get in between the eddie and the standing wave.

It gets pretty complecated (and I don't pretend to be qualified to know in much detail, or mathematically proveable terms and such), but you can picture all kinds of stuff happening, and really, whatever you can think of happening, probably is. It's not the direct path to the engine that you would think it is.

I understand what you are saying but the difference inbetween the stock snorkel air flow and say my TriangleATV snorkel is should be negligable. I would like to see some figures on air volume and such if there is anything.

Also, what about my carb question earlier in this post. Mikuni or Kehein?
