What are the butterfly valves on the exhaust system after the exhaust manifolds for? Is there anything that would happen if they were not working? Thanks

They are called "exhaust shutters".....<br />They keep your engine from ingesting water through your exhaust, under certain circumstances.....<br />They are cheap, I would reinstall new ones if possible...... ;) ......JK<br />* Some are easier than others, and do not require engine removal to perform the installation.....
