I'm in the process of deciding on engine upgrades. A stage 1 approach,bolt on stuff. Turbo, headers and intercooler for my 1988 930 turbo cab.

The question is: What about the catalytic converter? If I do the upgrades, can I keep a cat in place or do I have to forgo it? If I can leave it in place, would it defeat the purpose of upgrading the power?

Thanks,
