CES have developed a range of high performance box type exhaust silencers which have the following advantages over cylindrical type conventional silencers:

- Thermal cladding unnecessary
- Lower installation cost
Acoustic Performance
These silencers are designed to achieve a high degree of acoustic performance, which in turn is governed by the number of internal chambers or passes. In a typical installation, the performances achieved would be as follows:
(nb. this relates to noise emanating from the exhaust tailpipe only. Long length tailpipes will produce lower noise levels.)

- The silencers have a fully welded 2.5mm thick zinc coated steel outer skin and internal baffling. The internal chambers are filled with rigid 110kg/m3 high temperature rockfibre slab, retained in place with perforated galvanised sheet tubes.
- The inlet connection(s) are normally flanged to BS10 table D with off centre line drillings. The outlet can either be a similar flange or a mitred tailpipe of length to suit individual requirements.
- The silencer is finish painted with high temperature aluminium.
