When it comes to headers, many people tend to overlook the importance of port shape. It can be easy to assume that all ports are made equal and that any header design will do the job, however this is not always the case. Port shape does in fact play a major role in determining how much power is delivered from an engine and whether or not it’s equipped with enough airflow for optimal performance. Different engines require different types of port shapes depending on their size and design; a larger engine with more horsepower may need a longer or wider port than one designed for lower-horsepower applications. The right shape helps ensure maximum power delivery while also helping reduce turbulence inside the cylinder head which would otherwise cause air flow issues. Additionally, some specialized sport exhaust systems even use unique port shapes as part of their design which allows them to achieve higher levels of performance compared to more standard designs. All in all, when it comes time to choose headers for your ride make sure you consider port shape carefully so you get exactly what your engine needs!
