"mrbmwx5 has put 4.8is mufflers(left and right), each of the muffler is list priced at $819.40(see link below). If you are buying these from dealer, it will cost you over $1600 +labor. You still will not have as good sound as you will with Eisenmann or Remus mufflers for less price. Unless you can get some used mufflers, its not worth it"
