Exhaust Headers Fits Dodge Plymouth Small Block 273-360 5.2/5.6 for Shorty
A pair of shorty exhaust headers built for the Dodge, Plymouth, and Chrysler Small Block engines from 273 to 360 cubic inches, covering 5.2L and 5.6L variants. Constructed from stainless steel with mandrel bent tubing, it replaces the factory manifolds and ships as a complete kit with gaskets and bolts. Fitment is specific to listed models and years, and it is designed for off-road and competition use only.

What You Get
Key Benefits
- Mandrel bent tubing improves exhaust flow and reduces turbulence compared to factory manifolds
- Stainless steel construction resists rust and heat cycling better than cast iron or mild steel
- CNC machined flanges ensure a flat sealing surface for consistent gasket performance
- TIG and MIG welded construction provides strong, durable joints under high engine loads
- 2.25 inch outlet size allows faster exhaust gas exit, supporting higher engine RPM and torque
Why Buyers Switch
Problems It Solves
- Factory cast iron manifolds restrict exhaust flow and limit engine breathing at high RPM
- Mild steel headers rust at the flange and gasket seal within a few seasons of use
- Poorly machined flanges leak under pressure and cause vacuum issues during operation
- Universal headers require cutting, welding, and custom fitting, which increases labour cost
Where It Is Used
Application Scenarios
- Classic car restorers upgrading performance on 1970s Dodge and Plymouth muscle cars
- Racing teams installing bolt-on headers for short track or drag events
- Performance shops building custom street rods with vintage Mopar engines
- Online sellers needing vehicle-specific headers with a clean fitment list for resale
Buyers
Who It Is For

Comparison
Compared With The Alternatives
| Factory cast iron manifolds | The stock manifolds restrict flow and heat up faster, this header improves exhaust velocity and engine breathing |
|---|---|
| Mild steel aftermarket headers | Mild steel is cheaper but rusts at the flange and gasket area; stainless steel lasts longer under heat and moisture |
| Universal headers | Universal headers require cutting and welding, this one bolts on without modification |
Installation
Use Guide
- Confirm the engine is a Dodge/Plymouth/Chrysler Small Block 273-360 with 5.2L or 5.6L displacement
- Remove the factory manifolds and clean the cylinder head flange surfaces
- Install new gaskets and bolts; do not reuse old ones
- Torque flange bolts evenly in a crisscross pattern to prevent warping
- Recheck torque after the first heat cycle to ensure no leaks

What is included in the package?
One pair of headers, gaskets, and bolts. No additional hardware is included beyond what is listed.
Is this for street use or racing only?
This header is designed for off-road and competition use only. It is not intended for emissions-compliant street use.
What material is used and why does it matter?
Stainless steel is used for its resistance to rust and heat cycling. It outlasts cast iron and mild steel in high-temperature environments.
Are the flanges CNC machined?
Yes. Both inlet and outlet flanges are CNC machined to ensure flatness and precise bolt hole alignment.
Is this compatible with a 5.9L engine?
No. The fitment list covers 5.2L and 5.6L engines only. It is not designed for 5.9L engines with factory EGR systems.
