1991 GMC Sonoma Truck Exhaust Manifold

A cracked exhaust manifold is not what you want to have, so get it fixed fast or you’ll be sorry. Once an engine starts its exhaust stroke, the piston moves up the cylinder, decreasing the total chamber volume. As the exhaust valve opens, presurized exhaust gases escapes into the exhaust manifold, creating what is referred to as an exhaust pulse.
