Pypes DGU14S 2.5-Inch Small-Block Chevy Downpipe Pair for Factory 3-Bolt Manifolds

Pypes DGU14S small-block Chevrolet manifold downpipes

Pair of 2.5-inch, mandrel-bent 409 stainless downpipes for factory cast-iron small-block Chevrolet exhaust manifolds with three-bolt flanges. Pypes specifies 1964–1973 A-body and 1970–1974 F-body applications; the A-body range includes 1968–1972 Chevelle.

Match the manifold and heat riser

Designed to use the heat riser. If it is omitted, a suitable heat-riser spacer is required separately. Confirm the actual manifold outlet, flange and sealing arrangement on your engine. These are not header collectors or a big-block/LS-swap selection.

The pipes connect the factory manifolds toward the transmission crossmember. Length trimming may be required to match the rest of the exhaust. Test-fit before cutting. Mounting hardware is not included; plan the needed fasteners and connection parts separately.
