fixing titanium catback

My friend sold me his greddy titanium catback for a good price. Because its dented in two places on the axelback.

I tried putting on but it wont fit right. When everything is bolted on and tight. The midpipe hits against the driveshaft and the muffler tip is slanted to the rightside hitting my jdm bumper diffuser fins. I've had a Greddy titanium catback before in the past so I know how to install it correctly.

I had to loosen the axelback bolts a little bit to relieve the tension. By doing that, the midpipe wasnt hitting the driveshaft anymore and the muffler tip sat in the middle of the diffuser hole but it sat 3 inches too low. Plus the exhaust is leaking at the axelback flange so thats not good.

Would a certain muffler shop be able to fix the two dents? Or is it even fixable at all because its titanium.

local muffler shop WILL NOT know how to weld titanium - you have to flood the weld area with Ar... have to be TIGed in a Ar enviroment to do it right

The Greddy Ti exhaust piping is VERY THIN...looks like this can be heated with a torch and bent back into position..get yourself a Map Torch and a solid length of puiping to stick inside to nudge it back into shape, yes this can be fixed and welding Titanium is not like welding steel however a good welder can do it for you....check around I bet there is a race shop that can steer you in the right direction...
