Pipe Dent Removal

didn't need to cut mine at all.

try using dry ice. They use that over here to pop dents out of cars with hale damage. should be rather inexpensive to try anyway...

you wouldn't believe it....but THE simplest way is to freeze it! remove pipe, fill the dented part with water, not full...just enough to cover the actual dent and a bit, position it in your freezer chest so the water sits in the dent. You may have to do this a couple of times. My buddy and I did this for a large dent in his 4 stroke header pipe, took two freezes and the dent was gone. He looked up this trick on the net. We wouldn't have believed it if we didn't do it ourselves. we kicked ourselves for not taking pictures of before and after. its way cheaper and faster than sending it out.

That's a great tip and no harm in trying. Heating around the dent and and using ice or dry ice would work on the same principal if you don't have a big enough deep freeze for a pipe to fit in.

I have heard people using the ice method on 4T pipes. (seamless) But not many success stories on a 2T expansion chambers(much larger volume).
Keep in mind a 4T header pipe has a larger wall thickness and a smaller diameter than a 2T pipe. I think you're looking at two completely different types of dents.
Let us know if you have any luck with the ice method.

My brother made up some caps for the pipe ends, pressurizes the pipe with nitrogen and heats around the dent. They usually pop out with ease.
