Yup. Always toward exhaust.

I am amazed at how many people tackle engine rebuilds, that really should be getting help from an experianced hand It's pleasing to see that most have a go but most of the time they can do more bad than good! A bit off track sorry and arrow towards the exhaust as mentioned or the front of the motor.

You guys are all off on this one, the original poster is correct. The arrow on a Polaris piston points toward the magneto side of the engine. All Polaris factory pistons have the arrow pointing sideways, no way can you install it pointing at the exhaust. Even the cheap aftermarket OEM copies like Kimpex and SPI have the arrow cast to point to the mag side of the engine. The only pistons for Polaris that have an arrow that points to the exhaust that I have ever seen are by Wiseco. Just thought you'd like to know.

TOWARDS THE MAG SIDE!!!!! Like Irondog said, Polaris is different from everyone else. You pobably guessed this anyway since you actually can't put the arrow towards the exaust side. Below is a page out of the polaris service manual for those who don't believe.

My 800 Polaris Liberty is toward the exhaust side, stock pistons. I put aftermarket in my Liberty 700, also to the exhaust.

Sounds like Polaris decided to go with everyone else with their newer engines and change the position of the arrow STAMP. Why they decide to stamp their pistons different than everyone else is beyond me anyway. Mine's a 97... wonder when the changed...

The arrow toward the mag side is probably a Fuji trait...

mag. side
As long as the piston ring gaps end up on the intake side, you know youve got it right.
