i have a universal dual tip stainless steel remus exhaust i purchased from austria for my acura good sound not loud or obnoxious no drone on the highway and makes a nice european car sound i had it on a inline 5 and used it for six months full stainless steel paid around $450. I am gonna sell it to my buddy for $250 if it will work for his bmw with inline 6, I might use it on the crossfire if it does not sell. Here are some pictures of it on my acura.
