VAREX Adjustable Muffler XFORCE ESBM235VKCS Cat-Back Exhaust for BMW M235

VAREX mufflers that are remotely adjustable utilize our patented technology to combine the design of a stock muffler and a performance muffler into one compact unit.

A sophisticated butterfly valve mechanism that is electronically controlled is implemented to redirect the exhaust gas flow and vary between the two muffler types.

For a louder sound level, the exhaust flow is directed through the open path, producing maximum power with a robust sound level and near-zero resistance.

For a lower sound level, the exhaust flow is directed through the chambered path, producing a minimum sound level that gives you the best in-car comfort.

The angle of the valve is controllable and can be adjusted to stop at various points between sports mode and silence mode.

This gives you further freedom to set the optimal sound level according to your desired preference.

The VAREX motor and gear sets are located on the top of the muffler; they work as an integrated unit to drive the butterfly valve open and close.

The VAREX control unit features durable construction with water resistant plugs.

Installation is easy, with no hard-wiring required (in-car 12V socket included) for plug and play functionality.

A stylish remote key fob is included.

A dual muffler control harness is available separately.
