What You Get
Key Benefits
- 4.5 inch single collector increases exhaust flow and reduces back pressure compared to factory manifolds
- 304 stainless steel construction resists rust and heat degradation better than mild steel
- Silver finish provides a clean, durable surface that holds up under engine bay conditions
- Slip-on design allows bolt-on installation without welding or fabrication
- 4 into 1 configuration optimizes scavenging and power output across the RPM range
Why Buyers Switch
Problems It Solves
- Factory manifolds restrict exhaust flow and limit peak engine power
- Mild steel headers rust quickly at the collector and flange joints
- Universal headers require cutting and welding, which adds time and cost
- Lack of a ready-to-install collector delays build timelines for custom builds
Where It Is Used
Application Scenarios
- Performance shops building custom exhaust systems for modified engines
- Diesel and gas engine builders needing a durable, universal header collector
- Online sellers who need a photographed, non-vehicle-specific part with a clear spec sheet
- Tuning shops upgrading exhaust flow on engines with 2.36 inch primary tubes
Buyers
Who It Is For
- Performance parts distributors stocking universal exhaust components
- Diesel and truck accessory wholesalers serving custom fabrication markets
- Independent installation shops that build or modify exhaust systems on-site

Comparison
Compared With The Alternatives
| Factory cast iron manifold | The factory unit is heavier and restricts flow; this header improves exhaust velocity and power output |
|---|---|
| Mild steel slip-on header | Mild steel is cheaper but rusts at the collector and flange; 304 stainless lasts longer under heat and moisture |
| Welded custom header | A custom welded header requires shop time and skill; this one ships ready to bolt on |
Installation
Use Guide
- Confirm primary tube size is 2.36 inch before installation
- Clean all mating surfaces before installing to ensure a proper seal
- Use new gaskets and hardware to prevent leaks at the flange joints
- Torque bolts evenly in a crisscross pattern to avoid warping the collector
- Check for leaks after the first heat cycle and re-torque if needed

Answers
Questions About This Part
Is this part vehicle-specific?
No. This is a universal slip-on header collector and not designed for a specific vehicle or model year.
What size are the primary tubes?
The primary tubes are 2.36 inch in diameter. Confirm this matches your engine's header tubes.
Do I need to weld this on?
No. It is a slip-on design and bolts on directly to the existing header flanges.
What material is used and why does it matter?
304 stainless steel is used for its resistance to rust, heat, and corrosion compared to mild steel or cast iron.
What is included in the package?
One 4 into 1 slip-on collector with 4 O2 sensor ports. Gaskets and hardware are not included.
Can I get this with a different collector size?
Yes. Custom collector sizes and O2 port configurations are available on request.
Is this street legal?
We do not claim emissions compliance. Check local regulations before installing or reselling.
