Primera Exhaust??

I'm in Christchurch...

I have talked to a shop (Magoo Mufller) and they have done only one Primera and they said it was really loud...

I just want a sports exhuast with a nice sound...

No droning..and no kidney pounding....

Shall I just replace the last muffler with a free flow stainless one...

What brands are good and what are bad???
