We're just getting done laying out a set of long tube try-y for the 6.0 and 5.3 chevys. They will be going on the dyno next week. We're gonna package these with a programer that will allow the engine to work with the headers. The programer will be a hand held unit with the capability to receive down loads if you ad a cam, blower, or whatever. The headers seemed to react better to a custom tune allowing us to change spark and fuel curves. I'll get some pictures posted when I get em back on the truck. Hopefully tomorow.

Whatever happened to the results?

Yeah, another paycheck or two and I'm just going to order the SuperMaxx set from Dynatech.

Do most headers extend past where stock manifolds go? As in the long tubes? Would you need an exhaust shop to make the necessary mods for them?
