Hey guys I am moving to Texas in July and I know that it depends on the county you are in as to weather or not there is smog testing. So my question is if I need to how hard would it be to install high flow cats on my x-pipe. Would it be worth the money to just have an exhuast shop add the cats. I can get 2 Bassani High-Flow Catalytic Converter for 150 a piece, or get a MAC H pipe with cats for 370. Thanks for your input.
