Chevrolet Cast Iron Automotive Exhaust Manifolds
New! Modified "Tru-Ram” Cast Iron Small Block Chevy Exhaust Manifolds
Must run cast iron exhaust manifolds in your class? Or, tired of the hassle of headers? Our new Modified "Tru-Ram” Small Block Chevy cast iron exhaust manifolds combines the quiet, durable function of cast iron with the best performance ever available in a cast iron exhaust manifold.
Modified "Tru-Ram” manifolds make 6 more horsepower than stock "Tru-Ram" exhaust manifolds. They feature CNC machined port openings that will not block the large exhaust ports on aftermarket heads. Plus, the outlet area is machined for our bullet-proof Gasket-Less Adapter Pipes. Gasket-Less Adapter Pipes are available in 2 ½” and 3” diameter.
Yes, the Tru-Ram exhaust manfolds do make a bit more power than the Corvette Ram Horn manifolds listed below.
160-TR - Tru-Ram Exhaust Manifold - 1 only. Stock - $150.00 each
160-TR-MOD – Modified Tru-Ram Exhaust Manifold - 1 only. Stock - $225.00 each
Note: Our Gasket-Less pipe kits will only fit on the Modified Tru-Ram Manifolds.
