  • Loud-Quiet Switching

Wortec have designed and manufactured our own electronic volume switching exhaust system for the last 8 years and in that time the system has been regarded as one of the best performing systems on the market.

From the outset the systems design brief was for a system that would have the same high flow path in the loud and quiet operation so there was NO reduction in performance in either mode. Along with this performance the system must produce a volume on the quiet setting of bellow 94dB so the car could be used on UK race tracks with lower volume restrictions.

Added to these requirements was the need for the system to switch from loud to quiet without the need for the engine to be running so that it was possible for the car to be started in quiet even if left in loud when last used.

To make this possible an electronic valve was designed and operated using a remote control button so the system can be switched at any time, this added to the exhaust boxes which have the same 2.5" or 3" straight through path on both the loud and quiet path through the box means there is no change in performance on either setting. This also means the system is perfectly suited for high performance cars and especially forced induction where the same back pressure in both modes is a very high priority on turbo cars for reliable engine performance.
