Any competent muffler shop will have a selection of aftermarket Cats - all EPA approved and everthang.Date: Wed, 1 Dec 2004 11:42:41 -0800 (PST) From: Bettina Van Curen <[email protected]> Subject: [alfa] Catalytic converter for 164S Has anyone found a reasonable replacement for the cat on the 164? I am in California so it must be legal. As of this year ALL Alfas are test only in CA (or at least the LA area). Thanks, Tina
