These lightweight test pipes fit in place of the heavy OEM catalytic converters. Using a test pipe removes the flow restriction a catalytic converter places on an exhaust system while increasing the horsepower.
The silencing effect of the converters is also removed, enhancing the aggressive engine sound. Test pipes are ideal for track days and race application.
The centre section is made flexible on applicable models as an added protection feature against vibration damage to the header pipes and the Lambda or Oxygen Sensor Bungs are pre-installed and threaded.
