Description
Overview
The Flowmaster Scavenger Series Elite Header is a full-length, long tube header engineered to unlock the potential of GM Gen III/IV LS engines. Purpose-built to complement modern LS-1 and LS-6 engine installations into popular Buick, Chevy, Oldsmobile and Pontiac muscle cars, this header delivers an exact fit alongside the increased exhaust performance that swap builders and street enthusiasts demand. From the laser-cut flanges to the ceramic-coated tubing, every detail is designed to move spent gases efficiently and stand up to the heat of a hard-working LS.
Built for Performance
At the heart of the design are 16-gauge stainless steel primary pipes measuring 1-3/4 inch in diameter, running unequal length for optimized scavenging across the RPM range. The primaries feed into a 3.00 inch collector, and reducers are included to help tailor the connection to your exhaust setup. Heavy-duty 3/8 inch laser-cut flanges with round inlet ports provide a rigid, precise sealing surface, while the flanged attachment method and flat band clamping keep the system secure. Gasket-free ball flange exhaust connectors help create a clean, leak-resistant joint at the collector.
Finish & Durability
A Silver Ceramic coating protects the header inside and out, promoting heat management and lasting good looks under the hood. Combined with the durable 16-gauge stainless construction, the Scavenger Series Elite is built to endure the demands of a high-performance LS application.
