Does Installation Of MagnaFlow Universal Muffler Affect Vehicle Performance
Question:
Is the MF13743 compatible with a 460 motor. will I loose any power? will it wear out the catalytic converter before its time. will it effect my 02 sensors in a negative way? will it improve gas mileage positively.

I called my contact at MagnaFlow about the Dual Core, Universal Muffler XL Turbo Series, part # MF13743 for your 460 motor.
They told me it will increase the horsepower and torque from 2 to 5 percent. It will not affect the catalytic converter lifespan, and will not affect the 02 sensors in any way. The gas mileage change has not been tested so they were unable to tell me if it would be affected.
This is a weld-on installation. the inlet and outlet diameter is 3 inches.
