nytro exhaust

[saz]

has any one tried to remove the stock muffler and just run a straight pipe off the stock header? Will there be any performance increases or decreases, In a car open exhaust normally gives you power so in a four stroke sled why not? I know it will be load but is there any power gain?

The engine wants a little back pressure without it your bottom end power will suffer. and it will be so loud you wont want to ride it

X2, I had my TNytro straight piped and it was too loud for any trail riding and in my opinion sounded too much like a tractor. I personally like the sound of the piped Nytros, it adds some character to the Nytros otherwise bland sound.

Was there any power difference with a straight pipe?
