Thinking about a few motor upgrades, like cams, intake, fuel, and exhaust. A upgraded clutch is aleady in the future.

What would be some good upgrades for my motor, I mainly do trail riding, and alot of hill climbing, most on rocks.

What would be a good exhaust? I personally don't want something that is loud, after 4 or 5 hours on the trail that would do nothing but give me a headache.

A cam should be high on your list, it will wake that 800 up.

I am looking into mods as well.

Here is what I have found out so far:

I installed the RZR S series header into my factory muffler to keep it quiet. Noticed a large improvement off the line (I.E. torque increase) and a slight top end. Worth doing in my opinion. Also talked to HOLZ racing. They agreed the s header is a great upgrade if you want it to stay quiet and actually increases the HP more than most of the aftermarket exhausts they tested.

Large bore intake and Throttle body are next on my list. HOLZ offers these as well as others out there. HOLZ claims a 3 to 4 hp gain on a stock motor and 5 to 6 with mods. Not a lot but without going to a turbo or NOS you are going to be talking about gaining a little here and a little there for a total gain at the end of the project.
A cam should be on the list but be honest with the manufacturer about the type of riding you will be doing the most. A cam made for top end will be a waste if you spend most of your time in the woods on tight trails or running mud. Also when choosing a cam be realistic on how far you are taking the project. Are you going big bore? Going with a stroker crank? Or is this a bolt on only type of project.
I usually make up a document like a map so to speak to chart out my projects. To make the best choices along the way you need to know the end result you want. Do your homework up front, be realistic, set your budget, and you will be a lot happier and the project will flow much easier.
Just some thoughts to consider.

I would also try to stick with one company for everything, their parts usually match up better, and are made to work together.

Just cut to the chase and get our whole stage 2 or 3 kit. It comes with everything you are looking for, runs on pump fuel and can be tuned to run the stock exhaust or the muzzy exhaust (if you haven't heard the muzzy, it's not much louder than stock but it really performs)
