The 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 for an exceedingly robust and lightweight unit.

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 regularly tightened as is the case with aluminium. Also stainless can withstand far better, the constant oscillation and vibration that exhaust system must live with.

Stainless steel silencers have a very long life, exceeding by a large margin other metals that will often fall apart after a short running time. The higher specific weight is compensated by the thinner wall thickness that one can use. The only disadvantages are the higher cost of stainless plus it’s extreme toughness makes it very difficult to work with.
