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.
