DA engines achieve their high power with a tuned silencer system, as is the case with all high performance engines.
The large volume and the compact construction (large volume with small surface area) make these silencer units especially quiet. They are made from thin-wall stainless steel tubing, Laser welded and highly polished. The use of stainless steel throughout makes them extremely robust and lightweight.
Stainless steel is vastly superior to aluminium in two ways, stainless alloys can withstand much higher temperatures and are very much tougher.
To give an example, the header fixing screws can be firmly tightened down and do not need to be tightened regularly as is the case with aluminium. Also stainless can withstand constant oscillation and vibration that exhaust system must live with far better.
Stainless steel silencers have a very long life, exceeding other metals, that will often fall apart after a short running time by a large margin.
The higher specific weight is compensated by the thinner wall thickness that can be used. The only disadvantages are the higher cost of stainless andits extreme toughness making it more difficult to work with.
We can also supply a variety of header and canister combinations from other suppliers, please email or call with your requirements.
