What is straight pipe exhaust?

Straight pipe exhaust refers to an exhaust system on a vehicle that is designed without any restrictions or mufflers in the system. This type of exhaust system is typically louder and more aggressive in sound compared to a traditional muffler-equipped system. It is commonly used in high-performance applications where maximum horsepower and torque are desired. While a straight pipe exhaust can improve performance and add a unique sound to the vehicle, it may not be legal in all areas due to noise ordinances or emissions regulations.
