**The use of sports catalytic converters, replacement pipes and manual valve controls (CES- 3, EVCU-1) are not permitted on public roads in some US states and other countries. Please be sure to observe the legal regulations in the respective country/state. Sports exhaust systems that are not approved for use on public roads are intended exclusively for racing purposes and are designed to be used on private racetracks. Use on public roads at your own risk. Before installing an exhaust system, the buyer must ensure that the system can be used in their respective region. Capristo Automotive emphasizes that you should avoid to rev up your car while not moving! The exhaust flames that may occur could cause damage to vehicles and persons in near proximity!**
