Understanding Headers: Shorty vs. Long Tube for Your HEMI

Headers replace the factory exhaust manifolds — the cast iron pieces bolted to the cylinder heads. They're one of the most effective power modifications for the HEMI engine, but the choice between shorty and long tube headers has major implications for cost, installation, and what other parts you'll need.

Shorty Headers

Shorty headers (also called "short tube") replace the factory exhaust manifolds with tubular steel headers of similar length. The primary tubes are shorter and merge into a collector at roughly the same position as the stock manifold.

Pros:

• Bolt-on installation — uses factory mid-pipes
• Easier to install (2–4 hours)
• Lower cost ($600–$1,200)
• Often emissions-legal
• Better low-end and mid-range torque

Cons:

• Less top-end power than long tubes
• Typically 10–20 HP gain (vs. 25–40+ for long tubes)

Best for: Daily drivers who want a noticeable improvement without the complexity and cost of long tubes.

Long Tube Headers

Long tube headers extend the primary tubes much further, allowing exhaust gases to build more velocity before merging at the collector. This is where the big power numbers come from.

Pros:

• Maximum exhaust flow and power gain (25–40+ HP with tune)
• Better high-RPM performance
• More dramatic sound improvement

Cons:

• Requires a matching mid-pipe (factory mid-pipe won't fit)
• More complex installation (6–10 hours, or shop install recommended)
• Higher cost ($1,200–$2,500 for headers + mid-pipe)
• May not be emissions-legal in all states
• Requires a tune

Best for: Performance-focused builds where maximum power is the goal.

Key Brands

Kooks — Premium quality, excellent fitment. The go-to for serious builds. Their 1 7/8" long tubes are the gold standard for the 6.4L.

American Racing Headers (ARH) — Race-proven, great flow numbers. Known for their merge collectors.

Stainless Works — Excellent quality stainless steel construction. Great customer support.

JBA — Budget-friendly shorty headers. Good entry point.

Installation Considerations

Both types of headers require removing the stock exhaust manifolds, which means dealing with potentially seized bolts — especially on higher-mileage cars. Budget for at least $500–$800 in shop labor if you're not doing it yourself. Long tubes additionally require dropping or lifting the engine slightly on some models.
