here is a supertrapp exhaust, assuming its the 350, im sure they make it for the 400 too.
this exhaust is a quiet series but claims good torgue gains. you can add or remove discs to add horsepower or torgue.

hope i helped!

 

if your not pullinf much in 3rd, and not full throttel, try moveing the clip on the needle lower. also i use HMF utility exhausts 4 utility atv's. good flow but still quiet if you use the quietcore it comes with

You need to rejet for the K&N! The engine comes jetted lean from the factory (to meet emissions standards), and the K&N will put you over the top. You will run hot, and can melt your piston!

Get an aftermarket muffler, like the FMF PowerCore 4 and open up your airbox (if you don't run in the wet all the time)....and of course a rejet.

A very slick ester synthetic oil will also net you a little horsepower. I run Redline motorcycle, and also recommend Maxima Ultra and Maxima 530MX (for cold weather).

 

thanks for the web sites i like my bike just need a little more i ordered a fan for the oil cooler to from a four wheel drive rancher i was told this would help i understand cooler is better and all that but i dont see how that will help power i ride nearly everyday and everybody i ride with has fourwheel drive big cc bikes
