The most restrictive part of the exhaust system is the catalytic converter. It filters out the harmful byproducts of the combustion process.

While muffling the exhaust of an engine is a good thing for the health of you and your family, removing the catalytic converter is a much better way to avoid trouble and save the environment.

A muffler delete is usually cheaper than a whole straight pipe exhaust. A cheaper option is replacing the exhaust pipe of the catalytic converter and back (also called an aftermarket cat-back exhaust system).

As a result, the exhaust is able to exit through the muffler and into the atmosphere with more force. This helps to maximize the engine’s ability to push out maximum torque.
It’s also important to note that straight pipes can add up to 10 more horsepower to your vehicle.
