Exhaust manifold for Chevrolet 283/302/305/307/327/350/400 FlowTech

When tuning an engine, it's advisable to start with replacing the exhaust manifold. This component, integral to the engine body, is the first point of contact for exhaust gases exiting the cylinder. The manifold channels these gases into the exhaust pipe's initial section, leading them through the muffler or a series of sequentially arranged mufflers, before finally exiting through the tailpipe. This makes the exhaust manifold a critical starting point for efficient engine tuning.
