    What if I chose the 997.2 without cats?!

    Whilst speccing my C2SII, I was asked by my OPC if I wanted to opt for a car without catalytic converters. (I chose the PSE option) Is this normal? What would be the power/noise benefits if I chose not to have cats? What would the environmental benefits be having the cats considering the DFI engine is already quite low-emission? What should I choose?

    Re: What if I chose the 997.2 without cats?!

    i think you should keep the cats. Without remapping your engine computer, taking off your cats is not going to help you gain any power...
