These lightweight test pipes fit in place of heavy OEM catalytic converters. The use of test pipes removes the flow restriction that a catalytic converter places on an exhaust system, while increasing horsepower.
The muffling effect of the converters is also removed, enhancing the aggressive sound of the engine. Test pipes are ideal for track days and race applications.
On applicable models, the center section is made flexible as an additional protection feature against vibration damage to the header pipes and the Lambda or Oxygen sensor plugs are pre-installed and threaded.
Made from T309 (1.4828) stainless steel.
IMPORTANT:
The test pipes may activate a CEL (check engine light).
To deactivate a recurring CEL you will need to tune the ECU or use the 02 sensor extensions.
Recommended for off-road and track use only
Fits OEM/Capristo headers and OEM exhaust
Fits Capristo exhaust (muffler) and OEM/Capristo headers
