Any suggestions on how to take dents out of the pipe? I've already tried the dry ice method, almost took out a big dent within 2 tries but its very dangerous, and it didn't take out the smaller dents. When that didn't work I plugged up the bigger opening that goes into the cylinder and filled it with water and put it outside to freeze. I woke up the next morning to disappointment when it didn't work, but maybe I did it wrong? I know about the torch and pressurized air method but i don't want the rainbow burn marks everywhere on the pipe (there's a few dents, big and small)

I am not sure where you can send it but the bike shop I go to sends them out and from what they say they come back like new with no discoloration. Personally I think the rainbow gives it personality!

ha, I'll take that into consideration if it's pretty cheap. My last option besides taking it to a shop would be just to torch it and then re-plate or powdercoat it, but I'm sure that's expensive. I'm wondering if I did the frozen pipe method wrong... its supposed to freeze tonight over here where I'm at so maybe I'll give it another shot, this time halfway filled and without a plug

freeze method should work, HOWEVER, you run into the risk of breaking the pipe at the weld.
I used pipe repair.com I believe, 65 bux or so to remove dents, weld a tab and put it back to factory shape...

the freezing works but you'll have to check it often (every hour maybe, or more?) before it destroys the pipe.

oh crap, I filled the entire pipe with water and let it freeze overnight about 3 days ago, I'm glad it didn't break. Pipe repair.com, I'll need to check it out. Did you order a kit of some sort to remove dents?

no you send it and get it back looking all good and shinny

no, you ship your pipe to them, they repair it, and send it back to you

and it fits better than new

Looks like I won't be getting my pipe back for another 10 or 11 days, but I guess its worth it. Thanks guys I'll see if I can ship mine out this weekend

For what its worth, this may seem a little extreme, but a friend plugs the exhaust entrance with a wooden plug, and used another wooden plug with a air hose attached to it and heats up the dent with a torch. When its good and hot he pushes about 20 lbs of air into it and out comes the dent. I have not seen the process in person, only the results. Has anyone else tried it?

Good luck

Hell. That sounds easy enough (and a lot cheaper, too!) for a newb like me to do correctly!

I think the dry ice technique that I tried was extreme, and sort of a bad idea. The plug shot out like a gun and landed about 200 yards away I almost got the big dent completely out. The plugs I use are rubber expansion plugs, I hope these would be fine. And how do I polish off the burn marks and rust to make it nice and shiny again? Just a consideration if I plan on fixing the dents myself

If the finish peals you are done with a shiny pipe. I used a scotch bright pad to get the heavy stuff off and then used a buffing wheel on a drill and bench grinder to finish it. That worked ok but there is probably a better way.

I been wondering why these companies don't create a muffler that is pre-dented. Sure would save time!

And frustration!

if I were to use a wire brush to get the rust off, I would think that would expose bare metal and make it rust even more? Im thinking if I were to polish it afterwards it would prevent rust, correct me if Im wrong, but what should I use?

I used a cloth polishing wheel on the drill and grinder with a past and liquid compound.

Most dents won't effect performance...In fact some will increase power.
