How beat up can a pipe be to make it not worth sending in?

Look at the web page. Pipe that has been looked like it was ran over comes back looking great.

Pipes have "memory" when you

fix them. Best to have the bike

to make them fit properly. Using an

oxy acetyl torch, and air pressure

around 80, and up to 120 psi for

the tough bends, seems to work

well. Biggest problem is getting the

pipe clean inside.

Had one "blow out" a rubber plug 

from the silencer end a couple 

weeks ago when something ignited 

inside the pipe, which is what it is 

supposed to do, instead of blowing 

the seams out of the pipe.

Probably a patch of 

carbon that had some fuel residue 

in it. Launched the pipe out of a 

vice, and across the room. 

That was after a varsol soak, soap 

and water, and frayed aircraft cable

in a drill to remove carbon deposits

BOOM !        Be careful

I personally think that a 100psi is extremely  dangerous (100psi x area get it? Air is compressible ).  I think that way lower pressions would be sufficient and safer. My 0.02

No it does look like crap the welds are not very uniform if you look closely you can even see some gaps in the welds where they missed a spot.
