Lightning exhaust ?
Anyone ever try putting a complete Lightning exhaust on their 5.4 powered Super Duty, im talking from the manifolds back. I think im gonna try it, just curious if anyone else here has already done it.

I can't think that the manifolds are significantly different enough to make any power on a N/A motor, and the OE exhaust is probably just comparable to a decent aftermarket. I don't want to discourage you, but what are you expecting to gain?

I assume you're thinking of doing this on a regular cab 2-wheel drive F250? Even then, I'd be surprised if they fit. The bends and curves of the pipes won't be in the correct location.
Remember, the Gen 2 L's are a regular cab configuration on the smaller, F150 platform. And the exhaust is a side exit (passenger side) setup.
If your truck is a 4x4 you'll have no chance of it bolting right in.

I was just gonna try it because I have a brand new convertor pipe off of the lightning. I found out tonight it wont work. Im in the process of finishing putting a set of shorty headers on it and just really didnt want to put the restrictive y pipe back on it. The factory exhaust really looks like it chokes these trucks.

Another thing to think about would be the catalytic converters. The F150 is a fully OBD-II compliant vehicle, while the 2001 F250 in your profile is only OBD-I. It will/might not have the O2 sensor after the cat, and the Lightning should have TWO cats and FOUR O2 sensors.

For the gassers, I'm pretty sure it was across the board when the engines went 3-valve.
There are, however, reports of F-series trucks with California emissions (and those that aren't supposed to be) that have the third O2 sensor after the catalytic converter, which means they are (supposed to be) fully OBD-II.
I've also heard about Excursions setup that way too. I think they mostly have EGR valves too.
In some of the "green states" that follow the California emissions model (NY/MA/VT/ME I think) it's hard to get an OBD-I F-series to pass because there's no O2 sensor heater monitor, and no catalyst monitor. New York is one of them. If the inspector doesn't know to put in a weight code of over 8500 lbs for a passenger-plate pickup, it won't pass when the computer reads the OBD system.
