Comparison
Compared With The Alternatives
| Factory exhaust manifold | The stock manifold is heavier and restricts flow; this header improves exhaust velocity and engine response |
|---|---|
| Cast iron aftermarket header | Cast iron is cheaper but prone to cracking and corrosion; stainless steel lasts longer in harsh conditions |
| Universal header kit | Universal kits require cutting, welding, and fitment adjustments; this one bolts on without fabrication |
Installation
Use Guide
- Confirm the vehicle is a 2001-2004 Ford Mustang V6 3.8L and not another engine variant
- Remove the factory exhaust manifold and clean the cylinder head flange before installing
- Use new gaskets and hardware to ensure a leak-free seal
- Torque bolts evenly in a crisscross pattern to prevent warping
- Recheck torque after the first heat cycle to maintain sealing integrity
