which ones are better the longtube or the short tube? what really is the difference? where can i find them at for a 98

 

Lt's are, well, longer. they are better performance wise, but are not emissions legal. getting shorty headers will be better than your stock manifolds but really aren't necessary, either, unless you're getting some major air flow through your engine.

 

LTs are better, but only by a hair on V6s. Unless you're really packing some power, or your stock headers are shot, there is no need to swap them out.
