Axle back exhaust

MicntaeG35

So I have a 2011 370z nismo that I purchased a couple months ago and I love the car! The only thing is that the exhaust is just WAY too quiet! I'm going to buy a full cbe but I'm going to wait until my warranty is up. So in the meantime I want to buy an axle back set up (something quick and easy to install /uninstall). I've done a lot of searching and browsing on this forum but can't really. a decision. The 3 I've narrowed it down to are the Topspeed, Megan racing, and AAM. Now the question is, which one is going to give me the best sound? I know I'm not going to get the awesome exhaust note like from a full Cat-Back but I still don't want a high pitch Honda civic rice rocket exhaust note. If there is a thread I've missed explaining please point me in the right direction. Any help is greatly appreciated!!
