Cast Construction Exhaust Manifold with Machined Seal Faces SKU: QT41357

When your exhaust manifold starts ticking with engine RPM, leaking exhaust gases, or developing visible cracks, it's robbing power and filling your workspace with fumes. This cast construction manifold restores proper exhaust flow and eliminates those troublesome leaks that cause noise, reduced performance, and dangerous exhaust intrusion.

Why Cast Construction Matters

• Rugged cast iron construction withstands repeated heat cycling without cracking
• Precision-machined gasket surfaces ensure reliable sealing with proper gasket compression
• Flange-ready outlet design works with standard clamp-on and flanged exhaust systems
• Balanced internal flow paths maintain consistent backpressure for optimal engine performance

Proper installation starts with clean surfaces and new hardware—old gaskets and compromised studs lead to immediate failure on these high-stress applications. With over 55 years of exhaust system experience, S&H Parts knows the right way to restore reliable exhaust flow.
