Another option if you are interested in having the option of cat or no cat. Is that you can have a piece made for the tunnel under the car that can be taken out if you choose too. I talked with noyz boyz about doing this kind of installation and the quote I received for a high flow installed in this fashion was $200-$250. You can choose either a flanged bolt in design (same as how the flex bolts in) or you can go with the magnaflow slip over design.
