NOTE: This information is provided as a guideline to pipe size selection for peak performance
at full throttle levels.  For vehicles that are street driven on a daily basis, consider using the next
smaller pipe diameter for best results.  Smaller diameter pipes will produce low-to mid-RPM  
torque.  Larger diameters produce mid-to high RPM torque.
