What Does An Exhaust Do?
Your car engine delivers power by mixing air and fuel in the combustion chamber to create combustion. The air is sucked from the surrounding, whilst the fuel is injected in. The injected amount depends on the amount of air that’s available in the combustion chamber.
How Can Aftermarket Exhaust Increase Horsepower?
The general way of increasing horsepower is to increase the amount of fresh air in the combustion chamber. More air creates more powerful combustion – delivering more power to your wheels.
Types of Aftermarket Exhaust
The types of aftermarket exhaust vary depending on the amount of components the aftermarket exhaust replaces. For example, a header-back exhaust replaces the entire exhaust system from the exhaust header all the way to the tailpipe (to the back). I cover each of them in more detail below.
Pros Of Aftermarket Exhaust
An aftermarket exhaust has a wider piping. This provides better airflow – allowing the exhaust gases to easily escape from the combustion chamber which then provide more room for fresh air to enter. More air equals bigger combustion – which means more power delivered to your wheels!
Cons Of Aftermarket Exhaust
An aftermarket exhaust can be expensive – depending on the type you purchase. If all you look for is an improved engine sound, then install a cold air intake instead. Aftermarket exhaust is a big piece of equipment that could be expensive to purchase and install.
