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 percent 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.

Features and Benefits:

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