I used this before on a build, pics in this topic.
I found I need it again today and tried it on a chrome no-cat pipe.
No joy whatsoever.
That chrome pipe just won't bend and all I got was a sore back.
It did however work dandy on the black stock pipes.
Just a tip in case you find yourself needing just a little bend to fit and don't have a big bench mounted vise or torch and heavy duty gloves.
