OBX Muffler Silencer?

When I bought my Civic last year, it came with the riciest "OBX Type R Racing Sports" muffler. Does anyone know if there's a website to order silencers? Whereever I go, they only have the the silencers if you buy the muffler. I can't stand the sound, plus, I've gotten a warning from a cop.

if you can't find a silencer, go to a muffler shop and have them weld in a big resonator like 20+ inches long
