Can I start my car with no exhaust?

Why Do Engines Need An Exhaust Manifold? A vehicle will be able to run without an exhaust manifold, but it will not perform as well as it would with one. The valves inside of the engine are not designed to operate without any resistance. Over time, this will fatigue your exhaust valves and cause them to begin to crack.
