Hi Carpe, Our cats are not legal in Cali however we could sell it to you for "off road use" and definitely we could hook you up with 3-4 extra gaskets. Please feel free to call at 905-703-1557, order online at solo-performance.com or e-mail me at firstname.lastname@example.org. Thanks so much for your interest!
You may choose not or be legally able to answer this question because I live and register my 2008 Solstice GXP in California. I am considering purchasing a Solo high-flow cat. My question is, do the necessary gaskets come with the cat or must they be ordered separately? I thought I would get an extra set (I presume they are not reusable after extended use), because when it becomes necessary to have my car smogged for registration renewal, as I plan to remove the high-flow cat, replace it with the stock unit so it will pass visual inspection, and afterward, replace the stock one again with the high-flow.
