OK so I bought a 97 pacific Green Cobra today and when I looked under the car, the H pipe had only 4 cats. I know for shure the stock 96-98 GTs have 6 cats and the stock 99+ GTs have 4 cats. Is it the same rule for Cobras? Do the stock 96-98 Cobras come with 6 or 4 cats from the factory? Thanks in advance.
