A friend of mine is thinking about these. Does anyone know what they do to the power?
They claim up to 10 ft lbs of torque across the power band from 2000 to 4000, I have my doubts.

 

If you are looking at duals check out the Basani Power Curve headers.&nbsp\\; They are equal back pressure length for both heads and the chrome and look is awesome.&nbsp\\;
