Dent removal?
I bought a new FmF pipe over the winter and have already dented the hell out of it. Is there any easy ways to get rid of the dents?

On a 4t header you can fill it with water and freeze it overnight to push the dents out. The ends do not have to be pressure tight, just enough to hold the water in. I don't know if this will work on a 2t expansion chanber. It would probably take longer to freeze all the way through.
Some riders consider the expansion chambers to be a disposable part, as in they are so important to performance that it is not worth messing with a tweaked one.

They ain't that hard to get out.
For the big end, use an 1 1/2" drain test plug- made by Oatey and available in the plumbing section at your local home desperate. For the small end, you'll have to scrounge around for a short piece of tubing/hose that'll slide over, then find some sorta plug to cap the other end. I wound up using a piece of 1" rubber tubing and a 3/4" PVC coupling plug (That white stuff plumbers/landscapers use) then band clamps to double secure all the joints on the small end.
Once you have everything nice & tight, put your pipe in a vise and DOUBLE make sure neither end is facing anything important.
If you have an oxy acetylene torch, start heating the dents in a circular pattern till all glows red. The heat of the torch will expand the air trapped in the pipe, and as the pipe gets hotter, the dents will start to disappear.
If you don't have an oxy/acl torch, Mapp gas (The yellow bottle) will work, just takes a few more beers.. Just make sure you keep the torch moving and don't burn through..
PS I've done this on more than one occasion, no need for compressed air.
Relax, take your time & the dents will come out.
I'll go out to the garage tomorrow and take some pics of the stuff I used if ya need a visual..

The nice thing about Pacific Crest is that he has all the jigs to straighten the pipe out so it fits just like it did when it was new
