Does catback exhaust brand matter?

I'm looking to install a catback exhaust on my 03 WRX and I don't know if I should go for the name brands such as HKS, Cobb, Magnaflow, etc. or just go for a generic 3" SS system. I understand it all pretty much works the same, but I don't need it to be too loud, I just need it to complement the CAI, but I want it to last a long time too and fit like a glove.
