Why?            

A high flow velocity aids the complete expulsion of burnt gases. And it increases the amount of the air-to-fuel mixture being drawn into the combustion chamber.            

How?            

When exhaust gases exit the engine with a higher flow velocity, they create low pressure behind them. And this low pressure continues to suck out exhaust gases at an extremely high rate, creating a valuable cycle.            

Waste of Air/Fuel Mixture            

Your engine’s exhaust port opens up to expel exhaust gases from the combustion chamber. And it remains open for a short time once they’re out.            

During that time, unburned air/fuel mixture can escape directly into your exhaust.            

And this wastes fuel, and needlessly creates pollution.            

And the only way to prevent this waste is if the back pressure at the opened exhaust port is greater than the pressure in the cylinder.            

So it becomes clear that too much back pressure is bad. And too little back pressure is bad.            

You need just the right amount.            

WHAT EXHAUST PIPE DIAMETER IS BEST?            

Don’t be fooled into thinking that a bigger pipe is always better for power and performance.            

To strike a balance between low back pressure and high gas flow velocity, you need the correct pipe size.            

The industry has developed a table to be used as a general guide. It tells you the proper pipe diameter based on your vehicle’s engine size and horsepower.
