Mufflerectomy 

The act of totally removing the muffler and resonator from a vehicle and replacing with straight pipes, thus reducing the restrictions on exhaust flow, and giving the car a deeper, nicer exhaust sound. Usually done when new performance mufflers either do not exist or are too expensive.

Dietrich: Dude, there aren't any sport exhaust systems for my Jetta TDi.

Stefan: Don't worry about that crap, just give it a mufflerectomy.
