3" OD 16 Gauge Aluminized Steel 90 Degree Mandrel Bend Improve your vehicles air flow with mandrel bent exhaust components from Khaos Motorsports. A mandrel is placed inside the pipe as it is clamped and pulled around a die. This ensures the inside diameter maintains its shape and does not wrinkle. This creates a smooth ID that does not restrict airflow. Better airflow improves gas mileage, horsepower, and sound.
