What is a straight pipe?

A straight pipe is a type of exhaust system component made of a single, straight section of tubing. It is typically used to replace the stock muffler and catalytic converter in a vehicle's exhaust system in order to improve airflow and increase engine performance.

Straight pipes are popular among car enthusiasts who are looking to achieve a louder and more aggressive exhaust sound. However, they may not always be legal as they can significantly increase the sound levels of a vehicle, which may violate noise pollution regulations.

While straight pipes can provide a small increase in horsepower and torque due to reduced exhaust back pressure, their impact on overall performance will vary depending on the specific vehicle and modifications made to the exhaust system.

It is important to note that installing a straight pipe on a vehicle may void its warranty and can potentially lead to fines or penalties for violating noise regulations. It is recommended to check local laws and regulations before installing a straight pipe on a vehicle.
