I like my ess tune but I have the akra full evo system / tune. As others have stated, it appears as if you have the stock cats. It should pass smog considering it has the cats. Isn't it legal in ca to alter the mufflers as long as cats are in place? My car is registered in mn so I don't have these concerns.
