What information do you need to make my header?

Our custom headers are built to the client's motor specs. We will advise and fabricate the most effective header based on the information given. If it's stock, just list stock. We ask for the following information:



Head: Ported? Flow #'s?

Intake Manifold or ITB's: Ported? Flow #'s? Port Matched? Size?



Compression Ratio



Vehicle Use: daily? drag? road race?

Supercharged: y|n PSI?

Exhaust Size

How would a custom header allow my engine to perform better?

A Header eliminates back pressure that robs power to the motor. With our header's each cylinder gets its own equal length runner. This guarantees that at each pulse, exhaust gases will arrive through the collector spaced out. A header you might purchase off the shelf likely comes with four individual runners at a single size diameter. In comparison, all of our custom headers (not budget headers) are designed with 4 equal length runners of a specific diameter, then stepped to a secondary set of 4 equal length runners at a larger diameter. This creates a suction.

What are the benefits to having a megaphone/reverse cone?

The megaphone allows the gases to expand as they cool. The reverse cone increases the velocity of the exhasut gases, acting like a fingure over a hose nosel. When used with a full exhaust system this improves mid-range. When running open header it broadens peak power.
