Description

Overview

The Flowmaster Scavenger Series Elite Header is a shorty-style header engineered to replace the restrictive factory exhaust manifolds on GM Gen III/IV (LS) engines. Built to unlock the airflow your engine was designed to move, these headers deliver a direct-fit upgrade that improves throttle response, power and overall engine efficiency without the guesswork of a custom fabrication project.

Manufactured from stainless steel and finished in a durable silver ceramic coating, the Scavenger Series Elite is built to handle the heat and endure the elements. The ceramic coating helps manage under-hood temperatures while protecting the tubing for the long haul, giving you a header that looks as good as it performs.

Key Benefits

Every detail is purpose-built for performance and a clean, leak-free installation. The 1-5/8 in. unequal-length primary tubes and 16-gauge tube wall work together to scavenge exhaust gases efficiently, while the 3/8 in. thick, laser-cut flanges keep sealing surfaces true for a tight, factory-quality connection. A 2.50 in. outlet feeds into included collectors, and factory collector connections mean this header mates up right where your factory system expects it.

  • Shorty header design that bolts in as a direct replacement for restrictive factory manifolds
  • Stainless steel construction with a protective silver ceramic coating for maximum durability
  • 1-5/8 in. unequal-length primary tubes with 16-gauge tube walls for efficient scavenging
  • 3/8 in. laser-cut flanges with round inlet ports and a flanged attachment method
  • 2.50 in. outlet diameter with collectors included for factory-style connections
  • Flat band clamping type, plus gaskets and necessary M8 x 1.25 x 25mm hardware included

Installation & What’s Included

Flowmaster designed the Scavenger Series Elite for an easy, straightforward fit. Collectors are included, along with the gaskets and the M8 x 1.25 x 25mm bolts/studs you need to get the job done. Note that reducers are not included. With factory collector connections and precision flanges, the result is a direct-fit, leak-free installation that gets you back on the road faster.

Fitment & Compliance

These headers are engineered for GM Gen III/IV (LS) applications, covering 2002-2013 4.8L/5.3L and 2007-2013 6.0L/6.2L engines per the application guide.
