Is it possible to avoid a CEL with these headers & section 1 without a tune?

I've never understood if the Section 1 from SG includes the right bungs for the O2 sensors.

Is there a relatively simple way to install them and avoid CEL / tune?

Did you ever have them mounted with the stock X pipe and stock mufflers? If so, was it overly loud? Raspy?

Thanks in advance.

Cheers,
