Description
Overview
The Flowmaster Scavenger Series Elite Header is a long tube header engineered to unlock the full breathing potential of your Chevrolet Small Block Gen I. Built with performance-minded design and a durable silver ceramic coating, it delivers the improved exhaust flow and scavenging that dedicated small block builders look for. From street-strip combinations to weekend project cars, this header is designed to help your engine move spent gases efficiently while looking the part under the hood.
Engineering & Construction
Each header is constructed from 16-gauge tubing with a 16-gauge tube wall thickness for lasting strength. The 1-5/8 inch primary tubes route into a 3.00 inch collector, and unequal length tube design helps optimize exhaust scavenging across the powerband. The ceramic-coated finish in silver not only gives a clean, high-performance appearance but also stands up to the demands of an active exhaust system. A robust 3/8 inch flange thickness with round inlet ports provides a solid, flanged attachment to the cylinder head.

Fitment
This header fits D port cylinder heads, including ZZ4 crate engines, and will fit most angle plug heads including factory Chevrolet bow tie heads. Please note it does not fit 1967-1969 Camaros with air conditioning. Installation requires removal or modification of locking steering columns if equipped, and a new left side air conditioning bracket is needed. Bolt size is 3/8-16 x 1, and all necessary bolts and studs are included along with the collector and reducers to make installation straightforward.

Because the Scavenger Series Elite Header ships with its collector, reducers, and mounting hardware, you have what you need to integrate it into your build. The 3.00 inch outlet and collector diameter pair well with a variety of exhaust setups, giving you room to tailor the system to your goals.
