Tired of the hassle of running headers? Looking for the very best exhaust manifold available for the small-block Chevy engine? Our 2 1/2" Corvette "Ram Horn" manifolds are the hot ticket.
Top left: #162S-C Cast Iron Corvette Exhaust Manifolds.
Left: Enlarged photo comparing 2 ports. On top is the modified port opening of Part #162S-C Corvette Exhaust Manifold. Bottom photo shows the stock port opening.
There is a 4 to 8 horsepower gain with the modified manifolds.
"Ram Horn" design is the best manifold available.
Port openings on our #162S-C Modified Manifolds are opened up to match a Fel-Pro #1404 exhaust gasket.
Stock port opening size is 1.260" x 1.315", which is smaller than many cylinder head exhaust ports. When ordering please specify left or right side manifolds.
