Smashed exhaust

[Nouseforaname]

Thought i would post in here, more likely to get a better response.

So...... my bike had a run in with a tree root and now there is a god almighty dent in my expansion chamber. Its a cr125 with an aftermarket exhaust.

I filled it with water last night and dropped it into the deep freeze after reading about it online, but that hasnt managed to pop the dent out.

Ive read of a few other ways of popping them out but wondering what you guys recommend.

Cheers!
