Re: 986S primary catalytic converters - what happens if??

Hi, everyone! I'm thinking about installing an entirely new exhaust system on my 2000 S. Most aftermarket headers delete the primary cats, seemingly (unless they're Fabspeed and $$$$). What would happen if I installed an O2 sensor bung after the secondary cats and just shifted the O2 sensors to a position before and after the secondary cats instead of before and after the primary cats? I'd like to avoid a CEL whilst being a bit cheap.

Thanks and Happy Boxstering.

If you eliminate the primaries that's what you have to do.
In order to not het a CEL there needs to be an O2 sensor before and one after the existing cat (per side).
Happy Boxstering,

Thanks very much, Pedro. I really do appreciate it.
