Like Brian and Keith said the the '86-'89 USA stock headers are the same as the Euro headers that work well as they are but are large and heavy.

The early USA cars had something different that was terrible for exhaust flow. They looked like something off an old tractor from the early 50's... and were hooked up to engine case warping thermal reactors that came before catalytic converters.

Headers with no other change to the motor are usually good for 5-10 horsepower improvement and some weight loss in the back while looking nicer, but they really shine and make gains in power when you do all the other hot rod mods to increase air flow into, through, and out of your air pump/engine while injecting more fuel into the increased air flow.

Brian's word "enablers" is the perfect short description.
