If you put headers on and I know for a fact you have to have a tune otherwise it throws a code. my 2010 2SS had Kooks long tube headers and high flow cats had to get a tune which voided the powertrain warranty. I have know idea about California, but GM does not make long tube headers, so any aftermarket headers which aren't GM approved a void. I didn't care about the powertrain warranty some people do. Its like the old saying if you want to play you got to pay.
