Flowmaster’s Scavenger Series Elite long tube headers are designed to replace the restrictive factory cast iron manifolds. These high quality headers are manufactured from stainless steel and are ceramic coated for maximum durability. They feature 2 in. primary tubes, 3/8 in. thick flanges and incorporate Flowmaster’s popular 3-1/2 in. ball flange collector connections ensuring a leak free installation.

Like all Flowmaster products the benefits include improved throttle response, power and engine efficiency. Designed for an easy fit these headers include gaskets and necessary hardware for easy installation. Will not fit with Saginaw close ratio 825 steering box. Big Block frame stands and motor mounts must be used to ensure proper engine location and header fit. Requires removal or modification of locking steering columns if equipped.
