She is correct. There is a lot of pressure coming from your engine; in fact, it’s actually fire when the exhaust comes out at the beginning. You will need to have the exhaust manifold replaced because it’s not good for your engine to have a loss of pressure in the exhaust. I recommend having a certified mechanic, such as one from YourMechanic, replace your exhaust manifold for you.
