The QD Exhaust Modular System manifolds were developed in the race sector. The materials chosen and the manufacturing philosophy are the best technology can offer. The choice for AISI 304, TIG welded, stainless steel, together with titanium (aluminium, alternatively) and magnesium are born from the need to have a highly reliable, long-lasting product and, at the same time, as light as possible.

It is just from contests that the use of magnesium as the end part of exhaust manifolds comes. This highly resistant material is finished with a superficial treatment which makes it specially resistant to high temperatures and unchangeable in time.

QD rear silencers are equipped with the special GAS-EXTRACTOR system which exploits the Venturi tube principle. This system guarantees maximum gas flow while favouring maximum efficiency for all the time you use the engine. Said system, furthermore, optimises the efficiency of the acoustic insulation, with excellent sound results.
