Flowtech Rams Horn Exhaust Manifolds

4.29 out of 5 stars 21 Customer Reviews

Flowtech Rams Horn exhaust manifolds feature a tightly fit block-hugger design for popular hot rod and street rods. The cast iron construction is styled in the vintage "Rams Horn" design for maximum strength and engine clearance. The manifolds use smooth-transition, 1 5/8 in. diameter primaries for increased exhaust flow, which means improved performance and throttle response. The thick header flange pads ensure a strong, leak-free seal.
