I don't know if you would get the same sound as the Si because of the different engines. I plan on going with the Magnaflow exhaust for the Si because it has a two mufflers inline of each other. I think that the first muffler is or might be a resonator instead of a muffler, but, anything to keep the sound down would be what I'm going for. I really do not want the loud exhaust but would like a little extra HP.

 

hopefully it WILL make the same sound becaues i dont have that much money and i just want a exhaust sound but not loud at all - just like the SI

 

+ like infinaty

 

finale question
how much is the Apexi World Sport 2 ? is that for the whole exhaust system or just the muffler?
i am looking to get just the muffler and get a low sound not loud

 

300-500 depending on where you look and how hard you look.

 

I haven't been able to find the WS2 Exhaust for my 06 Si. I am stuck between the WS2 when it comes out and the Magnaflow.
