Two exhausts in one. Cruise quiet, then open the valve and let it breathe — switched from a key fob, on the fly, without touching a bolt.

This muffler houses a vacuum-actuated valve that redirects flow between a muffled path and a straight-through path. The wireless controller drives the actuator through a vacuum line, so the valve moves smoothly and holds position without constant current draw. Closed, it stays civil enough for early mornings and underground parking. Open, it gives you the full note under throttle. No tune, no exhaust swap, no compromise between the two.

Why it works

Two exhausts, one part. Quiet mode for the commute, open mode when you want it. Switch at any speed.
Wireless remote control. Two key fobs included, so a second driver in the household is covered.
Vacuum actuation. Smooth, progressive valve movement with no electric motor sitting in the exhaust heat.
Simple 12V power. One cable to the control module. No harness to route through the cabin.
304 stainless steel with a mirror-polished finish — built for heat cycling and GCC humidity, and it holds its shine.
Precision TIG welds throughout, with a sealed valve mechanism rated for continuous cycling.
