I got a 92 cx hatch that i just put a b18c1 in. I want a stock sounding exhuast and i heard that a gsr or type r is pretty quite. I also heard that apex world class and the mugen twin loop is pretty quite. How much louder would the apexi and the mugen be than a stock gsr muffler?

Also where can i buy a stock oem gsr or type r muffler. I have looked all over the internet

 

used parts nad classifieds, though the dealer will always have them.
