Buying advice

When choosing an exhaust manifold, prioritize fitment for your specific vehicle model and engine. Cast iron is durable and OEM-like, while steel is lighter but may corrode faster. Check if gaskets and hardware are included to avoid extra costs. If you need emissions compliance, ensure the manifold has proper catalytic converter integration or is approved for your area. For performance, look for tubular manifolds with smooth bends, but expect a louder sound. Always verify bolt patterns and port sizes before purchasing.
