Circuit Sport vs RSR vs Apexi Noir

[NSR250]

looking for an exhaust that is on the quiet side for a S14 w/ SR20.

I know that these three are on the quiet side. But which is the quietest?

Circuit Sport
RSR Exmag
Apexi Noir

I have only heard the RSR in person so I can't really compare.

I got a 5ziegen border III it is so nice and quiet...
I had it on a sr s13 , and all you could hear is air forced out and turbo spool....the first resinator is large like a muffler...
sounds great...

I have a Circuit Sport full exhaust (dp/catback) on my S13 and it was almost like my car wasn't on it was so quiet lol. It got to the point that it pissed me off cuz it was so quiet. I ended up taking out the cat and putting in a test pipe. IT'S STILL FRIGGIN QUIET!!! The fuzz doen't bother me so it's all good.

I got an HKS hi power at 2.5 inches. It is very quiet, alot quieter than i thought it would be. It doesn't rumble, it hums. When the exhaust is warmed up i notice it sounds more agressive. I may put in HFC to make it more growly

The welds on the circuit sports look pretty crappy in the pics i've seen. i'd go with the RSR or the Apexi.
