Quiet 5" muffler?

[Regcabguy]

Can anybody suggest a 5" QUIET muffler to replace the supplied droner on a stainless Magnaflow turboback system? My buddy's system is way too loud for his taste and the neighborhood's. He's ready to go back to stock,but I thought somebody out here could help. Thanks in advance.
