Review on Walker 82450 CalCat Catalytic Converter by Joe Fulce

Finding CARB approved parts can get expensive! When I saw legal CA catalysts selling for $300-$500 on most websites I wasn't happy. After much searching, I found this relatively cheap converter compared to all others. I took off the old clogged one, put this one on and done. Code P0420 no longer exists. I would advise you to buy additional manifold mounting parts instead of reusing the old ones. Other than that, this thing is a bargain for CA's legal side. Strangely, apart from the price, there is no difference to legality.
