Good to know about the fan, try to make sure to switch to all synthetic oils, if the tires are still in good shape, pump them to the maximum, and in general follow the 100 tips and tricks on the home page.
About the pipes, better flow is not necessarily bigger pipes, you need to find optimum sized pipes for the flow that your car is going to produce. To big, and the car is gutless at low speed, to small and the car overheats and bogs and sometimes chokes itself out There are some complicated formulas that I can find for you to accurately calculate the ID of the pipe you need.
