Borla + resonated test pipes is music. So i would say go Borla, but then again my opinion is biased because i hear it everyday.

The thing i love the best about the borla is it's fairly deep and quiet when normally driving. But it screams when you really push it.

 

rsr gt II... my car sounds like a race car... i love it some people think it's too loud (which it kind of is) but it comes with silencers. with the silencers in, it's almost too quiet so I don't use them.

 

You are welcome.

 

+1...i just traded for the xo2 and its really deep...i had the turboxs catback and that was extremely loud kinda miss the loudness of the turboxs tho

 

Since this has become a "mine's bigger than yours" thread, Billy Boat exhaust. With HFCs and Y-pipe, it is the most intimidating exhaust I have heard on ANY vehicle. It is deep, it rumbles, it screams, and it looks fantastic!

 

quiet deep = Nismo

 

My X02 is music to my ears

 

There's no replacement for displacement.... Get a bigger engine if you want a deeper tone.
