The Fiver developed a small hole in the muffler over a year ago. Rust, salt, moisture, and heat combined to turn that into a larger hole over the past year. The result is an increasingly louder vehicle which went from not noticeable to burbling like a hot rod muscle car. A new muffler came from Bavarian Autosport, and it was installed by a local Midas shop. Noticeably quieter, and feels a bit smoother.
