When it comes to torque and horsepower,
most vehicle manufacturers leave plenty of room for improvement. It
is not that these vehicles are poorly made, but companies usually
choose the most affordable options, especially when it comes to items
such as exhaust systems.
An aftermarket performance exhaust for
cars can free some of the power in your car's engine. That is because
these systems are designed to allow a quicker and more efficient path
for exhaust gases to escape. This means your engine will spend fuel
and air present in the combustion chambers faster. More fuel and air
burned equals more power created.
