These lightweight test pipes fit in place of heavy OEM catalytic converters. Using test pipes removes the flow restriction a catalytic converter places on an exhaust system, while also increasing horsepower.
The muffling effect of the converters is also eliminated, enhancing the aggressive engine note. Test tubes are ideal for track days and racing applications.
On applicable models, the center section is made flexible as an added protection feature against vibration damage to the header tubes, and the Lambda or Oxygen sensor plugs are pre-installed and threaded.
Made of T309 (1.4828) stainless steel.
IMPORTANT:
The tubes may activate a CEL (Check Engine Light).
*Recommended for off-road and track use only*
