Exhaust???

I have a 2015 900s an looking to buy an exhaust. Im trying to find something that is going to give that deep loud exhaust. I want it to be noticeable instead of sounding like a Prius driving by. Any suggestion?
Also does a exhaust an programmer void the warranty?

Low oil pressure when hot

I have a 2013 900 xp with oil pressure gauge installed. After 15-20 mins of driving pressure drops to 25 psi at cruise and 5-10psi at idle. After machine sits for a while and cools pressure back up. I was wondering where the pressure relief valve is and if it could be sticking open when hot.

exhaust header questions

I have a 2012 900 xp and at the bend for the mag side tube it had made a giant hole. bike was backfiring is how i noticed on decel -side not have alba stg 2 complete kit

So the questions are has this happened to anyone else?

Should i buy a used stock header?

Has anyone heard of or used UNIT SIX exhaust?-if so did u have to use header wrap or something since it is not coated?

What about using bikeman’s header?

Would I have to change my tune due to differ headers?

I would like to order soon so i can get back to riding asap.

2011 900XP Oil problem HELP!

Hello, I just purchased a used 2011 900 XP from an individual. It has around 140 hours on it with 1300 miles. The previous owner stated that the machine had been parked in the barn all winter and not driven so I decided to go ahead and service it when I got it home. When I removed the dipstick, I was surprised to see that the oil level in the oil tank was way over full. I thought previous owner had just over filled it. I removed the engine drain plug but I was surprised again to see that only about a quart or so of oil drained out. I pulled the oil filter, which was full of oil, and then went back and checked the oil tank, it was still way over full. I decided to pull the hose off that feeds the crank case to make sure there wasn’t anything blocking it and there wasn’t. All of the old oil from the tank immediately drained out into a catch pan I had.

I decided to put a funnel and hose on the crank case oil inlet and pour some oil directly into the crank case to see what would happen. The oil would not drain into the crank case. Why would this be? With the funnel sitting there half full of oil, I removed the coil wires (so the engine wouldn’t start) and turned the motor over a few times. The oil in the funnel very slowly drained down into the crankcase. Can someone explain to me why this would happen? If I remove the drain plug, and pour oil into the tank, shouldn’t it pretty much go straight through the crank case and run out of the drain?

I put a new oil filter on and the drain plug back in and put 3.5 quarts in but none of the oil has drained into the crank case. If I check the dip stick, it shows way over full so I know all of the oil is just sitting there in the tank. I am afraid to start it in this state.

Any help would be appreciated. I am concerned that there is something seriously wrong with this thing.

STM clutch tuning

so i am having trouble finding ant stm clutch setup info

can anybody with stm clutchs post there setups so we can start a thread where ppl can go to look for a setup close to there modifications.

i have a 14 xp 900 with 4000 miles on it

STM rage 6 and tuner secondary
alba stage 2 cams
alba inbox intake uni filters
slp exhaust
power commander 5 with alba’s tune
big horn two 27" tires

i currently have

Secondary – 46 helix/gold spring
Primary – 40gram weights with 1 washer in middle and 3 washers in bottom / gold spring

i currently bounce the limiter at initial stab of the throttle and then it pulls down to around 8100-8150 and holds there, alba says 8300 is targeted rpm

STM was no help for baseline. when i bought these clutches they were ordered for stock application and when my rzr was stock it would only pull 7700 rpm, so i know other people have had to adjust there clutches.
