Exhaust Header
Stainless Steel Exhaust Header for Toyota 75-80 Celica Pickup 75-83 Hilux 2.2L
A 4-2-1 lightweight stainless steel exhaust header for the 1975-1980 Toyota Celica Pickup and 1975-1983 Toyota Hilux 2.2L SOHC engine. It features 1.5 inch primary tubes and a 2.5 inch output with CNC machined flanges. The header is a direct bolt-on replacement for the factory manifold and ships as a complete unit with no additional components. It is not designed for 2WD Hilux models without modification due to torsion bar interference.

What You Get
Key Benefits
- 4-2-1 header design improves exhaust scavenging and low-end torque on older Toyota engines
- 1.5 inch primary tubes match the factory port size for a direct bolt-on fit
- CNC machined flanges ensure consistent sealing face flatness and reduce leak risk
- TIG and MIG welded construction provides strong joint integrity under heat cycling
- 3 stage polished finish enhances appearance and resists surface corrosion
- Lightweight construction reduces engine bay mass compared to cast iron manifolds
Why Buyers Switch
Problems It Solves
- Factory cast iron manifolds restrict exhaust flow and add weight to the engine bay
- Poorly fitted universal headers require cutting and welding, increasing installation time
- Rust and cracking in original manifolds occur after years of heat and moisture exposure
- 2WD Hilux models cannot fit standard headers without modifying the torsion bar area
Where It Is Used
Application Scenarios
- Classic car restorers upgrading exhaust flow on 1970s Toyota pickups and Hilux models
- Performance shops installing headers on vintage Toyotas for improved throttle response
- Racing teams using off-road headers on 2.2L Toyota engines in competition builds
- Distributors stocking vehicle-specific headers for the 1975-1983 Toyota market

Comparison
Compared With The Alternatives
| Factory cast iron manifold | The original manifold is heavier, restricts exhaust flow, and is prone to cracking under heat stress |
|---|---|
| Universal header kit | A universal kit requires cutting, welding, and fitting, while this one bolts on directly |
| Mild steel aftermarket header | Mild steel headers rust quickly at the flange, while stainless steel resists corrosion over time |
Installation
Use Guide
- Confirm the vehicle is a 1975-1980 Celica Pickup or 1975-1983 Hilux with 2.2L SOHC engine
- 2WD Hilux models require modification to clear the torsion bar before installation
- Use a new gasket at the cylinder head and turbo flange to prevent leaks
- Torque flange bolts in a crisscross pattern to maintain sealing face flatness
- Do not install on vehicles used for street legal operation in California or New York

Answers
Questions About This Part
Will this fit a 1981 Toyota Hilux 2WD?
Yes, but the 2WD Hilux model requires modification to clear the torsion bar. The header will not fit without this adjustment.
Is this header for street use?
No. This header is for off-road, competition, and racing use only. It is not legal for sale or use in California or New York.
What size are the primary tubes?
1.5 inch. The primaries match the factory port size for a direct bolt-on fit.
Are the flanges already welded on?
Yes. The header ships as a complete unit with CNC machined flanges already welded.
What finish is applied to the header?
A 3 stage polished finish is applied to all visible surfaces for appearance and corrosion resistance.
What is included in the package?
One complete header. Gaskets and hardware are not included. A new gasket is recommended for installation.
Can we get private label packaging?
Yes. Private label packaging and barcode labels can be arranged. Bulk cartons are available for container orders.
