ST ebay header and fuel economy Options

[dutchboy]

Thinking about getting an ebay header for my 94 ST, and wondered about the effect on fuel economy.

People have said that the ebay header moves power up into the higher rpms.

Now, will less power in the lower band mean better or worse gas mileage for city driving? How about highway speeds?

Also, how much does the ebay header weigh VS. stock exhaust manifold?

Thanks

They have those computers that you can hook up to your OBDII sensors, not sure how much they run tho. Most do math calculations, run close to empty, put X gallons, run close to emply again, Calculate miles from last fill up and divide by how many gallons were put it, you will need to do this 2-3 times to insure its accurate.
