Description
Overview
The Flowmaster Scavenger Series Elite Header is a purpose-built, long tube header engineered for the GM Big Block engine. Designed for enthusiasts who demand serious exhaust flow and performance, this Scavenger Series Elite header combines a proven long tube design with a durable Silver Ceramic coating to deliver both function and lasting good looks under the hood.
Built to a High Performance grade, this header uses unequal length primary tubes measuring 1-3/4 inch in diameter, feeding into a 3.00-inch collector for efficient exhaust scavenging. The 16-gauge tube construction and 3/8-inch header flange thickness provide the strength and heat resistance expected from a premium performance component.
Key Benefits
The Silver Ceramic coating isn’t just about appearance—ceramic-coated headers help manage under-hood temperatures while resisting corrosion for a longer service life. The unequal length long tube configuration is engineered to maximize exhaust velocity and scavenging across the RPM range, helping your GM Big Block breathe more freely.
Installation is straightforward thanks to a flanged attachment method with round inlet ports, a flat band clamping type, and 3/8-16 x 1 bolts. Best of all, everything you need to complete the job is included in the box.
