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 the least amount of added weight 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 treated with a special coating to make it extra resistant to high temperatures and thus more 'like new' as time progresses.
QD rear silencers are equipped with the special GAS-EXTRACTOR system which exploits the Venturi tube principle. This system guarantees maximum flow while favouring maximum efficiency for all the time you use the engine. The system also optimises the efficiency of the acoustic insulation, with excellent sound results.
