My friend told me his friend could make me an exhaust and it would be semi mandrel bent and would flow the same as mandrel. Is this true? Does it even exist? I always thought it was mandrel or crush. Thanks

 

You either use a mandrel to bend to tubes or you don't

 

Some exhaust machines are able to make smooth bends, but they "pinch" the tube in the process. Around the turns, the piping remains smooth but is constricted due to the bending process. If you've seen it, you'd know what i mean.
A lot of autoparts store pieces are like this.

 

that sounds like a way to get more money from you

 

Thanks for the help. I think I'll stick to my original plan of a full 3in mandrel bent.

 

good idea, maybe he means semi-mandreal by the outer edge is not pinched

but thats how crush bent looks so.
