K&N Air Filter
Dyno Jet Kit
Big Gun Exahust

These 3 together should bump you up 4-5 HP on a 15.4 HP engine, assuming you have the 400.

05 Rancher AT 400

 

when i jetted mine and had a uni air filter i probly gained 3 or 4 hp with stock exhaust. 350 rancher.
uni air filter
stage 1 dyno jet kit

But if your getting aftermarket exhaust id get a stage 2 jet kit would get more power.

 

it seems hard to find a stage 2 jet kit for the rancher 350. I've found many stage 1's, but no stage 2's.

 

on ebay theirs some that sell stage 1 and stage2 together for 49ish.
