[RICK LAKE]

jersey427owner Are you trying to register the car in NJ? Emmissions have to match the motor sometimes. You can use just Cats in the side pipes if you get the 3" round ones. You will not need mufflers. You might need 2 O2 sensor bung holes for computor to run the motor. Do you need 2 or 4 sensors?
The other issue is, is the motor stock or has work. May have to get a custom calibration to get through emmissions and then reload the better one for the car. Google cats. There are a couple of companies that make round tube ones. The easiest way is to get a set of side pipes and cut them open and swap the mufflers for the cats and reweld them. Send pipes out for coating. You will also need shields in NJ with side pipes. Leave the drivers seat out of the car at inspection if the car has only one roll bar. They will fail you for this. Rick L.
