ok, looking into putting on a full system,,, after researching it , the full seems better for the extra cash,,, but ,,, problem is which is the best bang with the least noise,,,dont want too draws too much attention,
i have already installed the KN power kit inot my 400,, i think im leaning towards the yoshi, or white brothers, any thoaughts on noise and other pipes that are good and also quite,,
thanks

 

Unless your looking to do major engine modifications...then a full system is an overkill. Your only going to add a half a horsepower at best, over a slip-on exhaust. So my recommendation is to purchase a WB E Series slip-on exhaust.

 

how is the white brothers for noise,,,
and which one,, the s bend or the pro meg,,, the s is much cheaper,, is just a silencer going too make a diff,,,
thanks

 

I like the "S" bend. It's not too noisy, your looking at about 94db. Stock is 88db I believe.

You'll notice a difference in the power. The best bang for the buck, is a 87mm piston, web cam, and a WB Exhaust all for about $800. (that includes all labor and tax too). It will add a good amount of power to your quad. Then start looking at suspension. You'd be surprised at how much faster you'll be able to ride.

 

also,, while im at it,, does anyone know where i could get a set of air scoops for my 440 ex,, i hear they halep cool the motor,,
thanks

 

i meant 400 ex, not 440,,,i wish,,,chow

 

Check Ebay. they're going pretty cheap on there.
