Elise S 2ZR-FE ROAD Exhaust System
Once you open up the exhaust on this car, it's surprisingly NOISY.
I've dropped the 7"diameter system altogether, kept the standard 8"diameter for road cars and designed a new H1 (ONE Helmholtz resonance chamber) 8"diameter system for quieter running on long journeys and in noise-averse countries like Switzerland.
The H1 has a double-skin the inlet end of the silencer and uses an internal support plate to form the chamber. This eliminates any chance of dronnnnnne. You can see the internal spot-welds around the double-skinned chamber at the inlet end of the silencer. It's still a straight-thru performance design, so no loss of power and a good sportscar exhaust note.
SELECT "H1 CHAMBER" IN THE BOX BELOW FOR THIS QUIETER VERSION.
