Answer 1

These pipes are for fresh air to inter the catalytic converter and make it run hot. A hot cat. converter is more efficient than one that runs cold. There should be valves at the end of the fresh air pipes at the motor to let air in, but keep the exhaust out.

Check e-bay. Check spell check too. Sorry, that was mean.
