You can get jets from your dealer or order them from an atv company. They go in the carburetor. Stick a big one in and work your way down.

 

Hey Rob, I owned a 1995 300EX for almost 7yrs. Maybe I can help you out.

More baffles = more noise and more power (if you set your bike up right)

Whenever your bike breathes easier you'll get more performance. The
less baffles, the more restriction on your exhaust.

You'll will need to re-jet. Probably one size up on the main jet, maybe two. Don't let somebody talk you into a whole jet kit. You won't need it, my bike ran great.

Along with your pipe, put on a ported air box lid, Uni air filter (with on outerwears cover over it to keep more dust out of the motor. And the key to making my 300EX fly,(for a 300EX that is!) a one tooth larger than stock front sprocket. Without the sprocket the bike will seem like it needs a sixth gear.

All these things won't cost that much (under $80.00),but you'll love the difference in the bike.

Hope this helps.
