Strangely, the out temp was only about 5 degrees cooler, not 20 like the in temp changed.
90% of the IC pipes in the 7.3 are steel, the insulation was there for sound and only sound... Go back and read the TSB's from the time.

Would there be any problems with cutting my cat converter off and running It a few miles to have a pipe welded back on???

Thanks,

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.

None of the 7.3's or 6.0's have one... Its more of a Dodge thing.

The very early 6.0s had one that was removable IIRC. But for only half a year, in 04 they became a machined in part of the turbo.

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