These manifolds have both the inlet, and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance. These manifolds have 25% Thicker walls than the crack-prone factory manifolds. The increase in thickness increases the rigidity of the manifolds and make them much more durable than the OE manifolds. These manifolds bolt directly to the factory y-pipe for an easy installation.

• Outflows the factory exhaust manifolds by 15%, improving performance and throttle response
• The machined ports match the factory gasket openings which maximizes exhaust flow
• Manifold mounting hardware is included for a hassle-free installation.
• 25% Thicker walls for increased rigidity and crack resistance
• Durable cast ductile iron construction
