Pictures say everything. Quality means everything! You truely get what you pay for. I don't mean to sound mean, but this would actually be considered a step backwards from the stock exhaust.
If you want great sound with very little money, remove your silencers or core your OEM/stock exhaust.
Hopefully you have a receipt for these; get your money back and spend it on a decent exhaust. To determine a decent exhaust, at least make sure the manufacture has metal brackets helping to secure the end caps. If they don't, it means the company is too cheap to use/fabricate them. The rivets directly secured to carbon is a dead giveaway of crap quality. In your case, there was no way to tell that they were not going to be packed correctly, but there are things to look for to determine quality. Lastly, any company that makes a decent product makes it a point to showcase their products with a proper logo. If you know you produce a good product, you want to show it off. If they cheap out on a $.10 sticker odds are they aren't proud of their product..
