Upon ignition, exhaust gases are pushed from the cylinder to the manifold, which forms an integral part of the engine body. From there, gases travel to the first segment of the exhaust pipe, pass through one or multiple mufflers, and finally exit through the tailpipe. For those diving into engine tuning, it's pivotal to begin with the exhaust manifold replacement. An upgraded manifold ensures optimal gas flow, leading to better overall engine performance.
