Introducing Varex™—the world's first remote controlled Sports muffler

VAREX mufflers combine both the design technology of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two.
  • Instantly control your exhaust volume with the press of a button
  • Easy DIY setup with easy in-car 12V (cigarette lighter socket) connection
  • Stylish key ring keypad
  • Maximum performance for the track and quiet stock like volume for the street
  • Automatic control kit which features an extra function that can adjust the volume automatically according to the pre-set RPM by users
