Nah, with those dents it doesn't look like its worth doing the freezer trick. Water is abnormal in that it is one of the few materials that will expand on solidifying (along plutonium and a few others).
It's to do with the way the hydrogen bonds interact with each other (without H-bonds water should be a gas a room temperature, so it's lucky we have them!), water undergoes a 4% expansion in volume, so you may need to do the freezer trick a few times.

REMEMBER! - water will expand along the whole pipe, not just where the dents are.

I dunno about powerband effects but it has to be damaged enough to risk damaging it further - if that helps.

Pipes can dent real easy. If they didn't they'd be too heavy for racing! It's not unusual to see people using old beat up pipes and winning races. Sometimes you can get one nasty knock and they cave in, then you wanna freeze it.

Remember, the more you work metal, the stronger it gets (notice how a ring pull gets tougher before it finally gets too brittle and breaks). So your pipe will probably a bit tougher for the battle scars.

I have been heating the pipe at the ding or dent with a propane torch and then pushing the dent back out from the inside. It works on the stinger also. You just need to find something the same size as the hole in the stinger. I use a drill bit the proper size and then clamp a pair of Vise Grip pliers onto the stinger, heat it very hot and then you can pull and bend the stinger back to it origonal location and angle. I have been very suprised the pipes that I have saved that I was sure where trash.
