California Smog legal X or H pipe
 

I have a 2002 4.6L Mustang GT. I live in California. I already have the MagnaPack Catback system, and I want to get an X or H pipe with cats. (if it will pass smog)

If it won't pass sniffer or visual, and I have to drop the X pipe with cats out and replace it with the stock H pipe to get it to pass. I will get an off road Bassani, MagnaFlow, or BBK X or H pipe.

Can I get a legal H or X pipe in CA? If so what brand(s)?

If I can't, what is the best brand for performance and value in an X or H pipe?

Or, would it be better to keep the stock H pipe in and do some other mod? ie: gears etc.

:confused:

Basically, it is illegal in CA to change cats period unless they are damaged or not functioning properly. In my experience they don't look under the car when you do a smog check. There are CARB numbers on the cats themeselves on my BBK short H-pipe on my '00 (for longtubes), but getting CARB approval takes time and money, so I doubt if the whole H-pipe itself is legal, which is probably the case for most of the ones out there for new cars. You may want to check Bassani as I believe that is what comes stock on Cobra R's and therefore must be legal for use in CA.
