DESCRIPTION

This universal matched pair of pneumatic vacuum‑driven valved mufflers delivers two‑in‑one exhaust sound tuning for modified vehicles.

The vacuum bypass valve switches smoothly between two modes: closed valve for quiet, civilized street‑driving tone, open valve for loud, aggressive racing‑style exhaust growl. Mirror‑polished stainless steel housing adopts optimized internal chamber design to keep exhaust flow smooth. Complete remote‑controlled vacuum system is supplied, including vacuum pump, wireless remote controller and full wiring / vacuum hose assembly for straightforward setup. Multiple pipe diameters and two stainless‑steel material grades are selectable to satisfy different modification requirements.
