More Whistle??
Gauges dont lie and the insulation kept the heat inside the tube. Aluminum sheds alot of heat, but if it is wrapped in insulation it cant. This is what happened to me after I took mine off, so it is safe to say that it would do the same on any other 7.3. Strangely, the out temp was only about 5 degrees cooler, not 20 like the in temp changed.
you should be just fine running catless. it might be really loud in the cab with the exhaust exiting their though
2003 7.3 turbo is the same as a 99.5 turbo... no differance at all...
if your talking about a 6.0 turbo, it will not bolt on, you would need a complete mounting kit and it would not be worth the trouble.

Not correct, the only differance was the turbine blades, the 03's had 11 and the 04 and up had 13...
