AMG mufflers are expensive. I believe they are north of $1000 for either the C43 or C36 versions. From what I've read, the AMG mufflers don't add much in terms of sound. Some have complained that they are just expensive versions of stock Mercedes mufflers with chrome tips. I can tell you from my own experience that Brabus mufflers do add a very deep growl. I've heard the same can be said for Lorninser. Any of the Mercedes tuner mufflers (AMG, Brabus, Lorinser, Renntech or Carlson) run from $700 to $1200. I've read posts from others who say Remus and other generic aftermarket mufflers also produce some desirable noise. They are also much less expensive, usually under $500.
