Show original supplier description
The Flowtech Long Tube Header offers a combination of performance and value for specific Chrysler, Dodge, and Plymouth vehicles. The 5/16" flanges are equipped with sealing rings to ensure a leak-free connection. Constructed from durable .049 cold roll flash mild steel tubing, this header is finished with a high heat-resistant black paint for a discreet look. It includes all required mounting hardware and gaskets, simplifying the installation process. The header features a 3-bolt flange collector with a 3.00" diameter, and a reducer is included to a 2.50" outlet diameter. Primary tubing diameter is 1 5/8" (1.625"). The product is compatible with 1972-1974 Dodge/Plymouth 2WD & 4WD pick-up trucks (1/2 & 3/4 Ton) and 1974 Ramcharger/Trailduster 4WD models equipped with 273-360 cubic inch engines. It is important to note that breaking in an engine with ceramic-coated headers will damage the coating and void the warranty; Flowtech recommends using cast iron exhaust manifolds or old headers for initial engine break-in.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.
