These lightweight test pipes fit in place of heavy OEM catalytic converters. The use of test pipes removes the flow restriction a catalytic converter places on an exhaust system, while increasing horsepower.
This version includes custom hand-stitched heat blankets to reduce under-hood temperatures while protecting surrounding bodywork, hoses and painted surfaces from residual heat damage.
The deadening effect of the converters is also removed, enhancing the aggressive engine sound. 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:
Test pipes can 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
