may be a little off topic, but does anyone know whether you don't legally need a cat for a dedicated LPG car? heard it somewhere before, not sure though.

No need for Hi Flow Cat, standard cat is good for 160+rwk and I don't think you are there with an EL XR6 with only 2 1/2" cat back. Waste of money unless your old one is stuffed and then it's cheaper to get a stock one anyway.

there only good if your after big power or running headers otherwise leave the stock cat there.. then if your going header's stay with a 2 1/4 high flow to keep back pressure or you'll lose down low..
