I bought a new pipe for one of my vintage bikes recently, but when it arrived it had a slight flat spot where it slips into the exhaust flange. I don't want to go through the hassle of shipping it back and waiting for another one, so my question is what tool would work best to put the curve back in it?

If your lucky enough to have a big socket that you can fit in and tap around or go to your local exhaust shop and get them to open it up with there pipe bender....take the flange with you, cheers John.

I hadn't thought about a large socket. Thanks Davey! :)

If you don't have a socket quite that big you can use something slightly smaller as a 'dolly' and holding it inside the lip, tap it gently with a small hammer and it will round itself up again.
When sealing flanges we use black silicon roof & gutter sealer on non EFI stuff. It's cheap and works a treat and burns to a nice carbon gasket when it gets hot. Don't use glass and tile sealer as it has an etching agent to help it grip and will rust the steel away. It will have a vinegar smell.

you could try a builders plumb bob its shaped like a funnel and its made of steel
give it a tap down with a hammer it will put a curve back in it.
