Answer> These specially designed catalytic converters still do the job of reducing and controlling vehicle tailpipe emissions but allow a better flow of exhaust gases making a more power and sports car sound. The factory computer is designed to read the exhaust gasses in the catalytic and automatically make engine adjustments to fuel, air and timing so that the car runs consistently better in all types of conditions. Including these with a complete system is the another way to gain the maximum performance and added sports car sound.
OEM catalytic converters are often 500CPSI to 700CPSI and very expensive and very restrictive. If the OEM catalytic converters fail/break why should you spend spend several thousand dollars/EUROs the same low performance restrictive cats. More.
