Hey guys i was wondering if any of you live and califorina and have changed exhaust systems? What type of system did you get that let you pass emissions regulations (or not pass)? Is the only awnser a cat back system, and if so will it have as much proformace effect as other? I know that i have to leave my cats in if i was to pass emissions, but are there some proformas systems that come with cats and the whole deal?
Thanks in advance any input would be great.

General emissions rules for california state that exhaust system must exit from the original place it did when you bought your car...basically, no side pipes. Also, there are noise restrictions. As for smog stuff, you'll need to keep your cat on your car and the 0x sensors.

Also, when you look at new exhaust systems, usually there is some kind of disclaimer from the manufacturer that states "not street legal" or "not approved for California". Check that out.

No mods - - - very happy as is!

No squeaks or rattles... unreal!
