What does ASP need to know about my motor set up?

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 for the gases to naturally expand, the reverse cone condenses and speeds up the gases which will efficiently remove the combusted gas out of the header supplying mid range power.

What are my payment options?
