You can go through the hassle of getting another one but there is the risk that that will receive damage as well even if its reinforced. Just my .02c.
+1; while it sucks I have never had any issues with Tishcer and have bought ALOT of stuff from them. But really, it probaly took longer to make this post, when you could've put the muffler on. As the other guy said I wouldn't worry about the bent ground strap bracket as it'll work fine. The bent connecting pipe is not too bad either. I know it sucks to spend $$ and have shit happen, but that's just it, shit happens.
At least you're able to afford an M and a 3k muffler!
