i'm pretty sure they said running the exhaust out the back made the yamaha sleds "balanced" when they came out....and now keeping all that weight up front makes the sled "balanced"....which is right?
Depends on what sled it is. It might be balanced in the nytro chassis to go out the back but in the srv chassis it might be better out the front. Two different animals.snoway said:i'm pretty sure they said running the exhaust out the back made the yamaha sleds "balanced" when they came out....and now keeping all that weight up front makes the sled "balanced"....which is right?

A smooth bend with the relatively big pipe diameter and bend radius visible in the pictures does not necessarily rob horsepower. Then I would be much more worried about the silencer. Any silencer designed to meet current noise rules is much more of a flow restriction than a smooth bend.dudester4 said:i will guarantee you that the power will be down how can you compare a straight, free flowing exhaust to one that bends a 90 degree.
Throttle Jockey said:why the is exhaust set up on viper the way it is? Pretty simple
no ice build up
no replacing donuts
no cracked pipes
better balance of the sled.
this is not the same as nytro,
Suckur said:The reason for not having a rear facing exhaust is the gas tank. Have you ever weighed a full tank of gas? That's the reason they are long and low and directly on the tunnel. It's to lower the centre of gravity as much as possible and distribute the weight of the fuel evenly along the tunnel and helps to counter balance the engine. A rear exit exhaust means a high gas tank and increases the COG which would make handling worse. It's part of the reason Yamaha's are so tippy, especially with a full tank.

These sleds will be within 15# of each other and everything but the exhaust weight distribution is comparible so ....same animals.

what ?...isn't alla that viper exhaust plumbing under the fuel tank????....then it does a 180 and shoots vertical for a foot er so and then into a huge suitcase muffler placed at a high CG.
