Exhaust - Muffler Question

[iLachva]

Don't know if this is the correct place to ask this question..

Well, I need some help choosing muffler tip.
I'm a vios driver with auto tranny.
What kind of muffler should I choose?

Cause I went to a shop and they have this M7 muffler and Racecraft muffler which both is good but yet pricy !

And I saw somewhere in the internet they promote their exhaust shop too..
But the price is half more cheaper.. And I asked them what's the brand and they answer me they don't tag brands for some reason..

So I need some advice .. What's the difference between these two ?

What I mean is the branded one and the no-brand one?

branded ones from japan, no brand ones are local,china or taiwan made. the fibre inside the muffler does not lasts long.
