cali smog Options

[Akira_g4]

my friends brother just got a new muffler on his civic and ive been thinking about getting a new muffler for my celica soon. keep in mind were pretty new to fixing up cars and were just learning about our cars. And i was wondering if after putting in a new muffler, would the celica pass CA smog? im assumeing it would pass since there are tons of people on the streets that have aftermarket mufflers, but just to make sure im asking you guys.

Cali smog is really easy to understand, if your just changing the muffler. Fail.

ANY exhaust mods are illegal.

but if your redoing piping and stuff and only getting smogged at a test only station they wont care about your muffler. Only police will for noise violation (i believe is 93.1 db's) dont quote me on that. But if your redoing the piping from headers/removal of cat and you go to a big smog shop you will fail. A muffler shouldnt change your smog levels at all, but make sure you have your igniton componants up to date and running a fuild called "Guarentted to pass" helped me pass with my GEN II JDM 3sgte. It burns excess carbon off your cylinder walls.

if you need any other help, shoot me an AIM at Uriiko001. Hope this helped some.
