I had just had my 5Zigen Fireball muffler put on my CRX the other day, and the silencer that plugs into it was the thing that made it sound much much better. And I didn't tighten it down! i went out to my car today, and the silencer is gone!!! Where can I find another one? I only need the silencer. where can I find this without buying the whole muffler again???
