Does a New Exhaust Improve Performance

Basically, by replacing the standard exhaust with an after-market performance muffler or exhaust system, you will boost your car’s engine efficiency from 2 per cent to 10 per cent. This extra efficiency can be used to either increase your car’s horsepower or improve its fuel economy.

Can changing exhaust increase horsepower?

To put it simply – yes. An aftermarket exhaust can provide additional horsepower to a car. They work by providing a better airflow for exhaust gases to escape the combustion chamber – providing more room for fresh air to enter and create a bigger combustion on the next cycle.

Do new exhausts make your car faster?

An aftermarket performance exhaust can free some of the power in your engine. These systems allow for a quicker, more efficient path for exhaust gases to escape. This means your engine “breathes” better, so spent fuel and air exit the combustion chambers faster.
