The pics dont work could you post them for me? Could I use water instead? Kinda like the hydroforming exhausts?

Thats an odd place for a dent to be unless it happened during shipping? It might be there to keep from rubbing something?

Not sure who made it, sorry :(

I was kind of thinking the same thing but I'm not sure. What kind of manufacture would dent a pipe for clearence was my second thought though.

I use a stud welder and special slide hammer, then finish the surface with a body hammer.

You'd be surprised. The entire side of the pro-circuit CR500 pipe is completely flat from the factory so tht it doesn't stick out past the radiator shroud where you could burn yourself on it. I bet thats actually a pretty bad hit on performance too even cause its a BIG area I bet about 8 inches like 2-2.5 inches wide

I have heard of puting dry-ice on metal to pop dents out. Seems plausable since cold contracts metals but Ive never tried it.

My Yamaha YZ80's stock pipe came with a couple dents in it from the factory, near the gas tank area.

heard of guys drilling holes from other side and using a punch or something similer to bang it out then weld up the hole.

Yeah, I've actually seen that work on hail damage on cars, not sure if it would work on a pipe though, interesting concept. Anybody tried this? Wish I hade a dented expansion chamber laying around to try that on.
