<strong>2.</strong>With the stock exhaust removed from the catalytic converter rearward, the new Magnaflow system can be installed. The kit comes with long and short intermediate pipes that go between the catalytic converter and muffler. The longer pipe is used on longbed trucks, while the shorter pipe is used on shortbed trucks. Three-inch-diameter clamps are used on the intermediate pipe at the catalytic converter and at the front of the muffler. A hanger bracket is welded onto the intermediate pipe and it mounts to the OEM rubber isolator.
