This build includes custom hand-stitched heat blankets to reduce under-hood temperatures while protecting surrounding bodywork, hoses and painted surfaces from residual heat damage.
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 increasing horsepower.
**Product image is representative, final images coming soon**
The silencing effect of the converters is also eliminated, enhancing the aggressive sound of the engine. Test pipes 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 pipes and the Lambda or Oxygen sensor plugs are pre-installed and threaded.
Made from T309 (1.4828) stainless steel.
IMPORTANT:
*Recommended for off-road and track use only*
Test tubes may activate a CEL (Check Engine Light).
To disable a recurring CEL you will need to tune the ECU or use our OBD Wizard
**The use of racing catalytic converters, replacement pipes and manual valve controls (CES-3, EVCU-1) is not permitted on public roads in some US states and other countries. Please ensure that you observe the legal regulations of the respective country/state. Sports exhaust systems that are not approved for use on public roads are intended for racing purposes only and are designed for use on private racetracks. Use on public roads is at your own risk. Before installing an exhaust system, the buyer must ensure that the system is permitted to be used in their region. Capristo Automotive stresses that you should avoid revving your car when not in motion! The resulting exhaust flames could cause damage to vehicles and people in the immediate vicinity!**
