there is a huge difference between an intake port and an exhaust port in terms of how air or spent exhaust gasses flow through each port respectively. Intake port runs cool with air fuel mixture and requires a ruff finish to help with fuel atomisation. Exhaust gasses flow way faster than the intake port dose. The exhaust port also is affected by thermal energy effects. Also thermal heat transfer into the cylinder heads is reduced with the smoother exhaust ports and reflective surface. The next step beyond this is a thermal coating in the exhaust ports..
