Muffler? Yes? No?

[Shobzz09]

Hi guys,
I was wondering if instead of getting an exhaust, I could get just a muffler??? Will it change the noise? If so, then what type of noise will it make?
Heres a Link of what I was deciding to get!
EXHAUST MUFFLER EXTENSION VOLKSWAGEN LT LUPO POLO 4037 | eBay

What do you guys think?
Thanks
