I have had long tubes since day one. Kevin Jander's car always made at least as much power as the 55 without them (most years he made more). If you run long tubes with the stock transmission that has the bellhousing made as one with the transmission you have to pull the engine to change the clutch. If I drive all the way to Hallett and lose a clutch on Friday I don't want to be going home just due to a bad clutch. This is why I run a Quicktime bellhousing and a T5 or A5 or TKO600 or TR3650. Every time I have an engine go South I ask myself why I still have the damn things on the car.
