Brockett Built 4.7L 2UZ-FE Mid-Length Headers

For Lexus GX470 & 4th Gen Toyota 4Runner (VVT-i & Non-VVT-i)

The 2UZ Header Game Has Officially Changed

Introducing the Brockett Built Mid-Length Headers, engineered specifically for the 4.7L 2UZ-FE V8 found in the Lexus GX470 and 4th Generation Toyota 4Runner.

Designed using full 3D vehicle scans, precision CAD modeling, and real-world testing, these headers deliver measurable gains in torque and horsepower while maintaining OEM-level fitment, reliability, and serviceability.

Built by a fabricator — for people who actually use their trucks.

Why Mid-Length Headers?

Unlike short-tube or oversized long-tube designs, Brockett Built mid-length headers are optimized for:

• Strong low-end torque for towing and off-road use

• Improved top-end power without killing drivability

• Proper exhaust scavenging with OEM-style clearance

• Bolt-on fitment without cutting, hammering, or guessing

These headers are designed to work where these trucks live — on the street, trail, and under load.

Technical Specifications

• 1.625” primary tubes – ideal torque and horsepower balance

• Mid-length design – OEM clearance with real-world gains

• True 4-into-1 merge collector with integrated spike

• 2.5” high-velocity outlet flange

• SAIS-ready ports with threaded plugs for easy SAIS delete

• Works with naturally aspirated and supercharged setups

• Compatible with VVT-i and non-VVT-i 2UZ-FE engines

• Direct bolt-on to stock or aftermarket Y-pipes

What’s Included

Every header set will include:

• New exhaust studs

• High-quality exhaust gaskets

• O₂ sensor extension harnesses

No reused hardware. No last-minute parts runs.
Everything needed for a clean, proper install is included.

Built the Brockett Built Way

These headers aren’t mass-produced, outsourced, or guess-fit.

The GX470 and 4th Gen 4Runner finally get headers worth installing.
