Scenario: Stock motored '91 LX (I mean bone stock), with a stock cat-back, and offroad H pipe, which will make more power/torque? Stock headers, aftermarket shorties (1 5/8"), or longtubes (1 5/8")? All with offroad H pipe, and stock cat-back. Anyone have dyno graphs or links to one? How much of a gain or loss with shorties or LT's vs. stock headers (both TQ & HP)?
