KZ has no shortage of exhaust systems Sarno

Testing noise is loud in the paddock for the World Cup at Sarno. Measures published on Friday during free practice show substantial differences, from 102 to 115 db in KZ2 and 103-112 db in KZ1, with a maximum allowed value of 108 db. The latest models of the leading suppliers of silencers pass smoothly under the bar set by the CIK.

Devil caused a sensation with its scoop system attached to the tube end of the EVO D.Racing developed for fast tracks like Sarno. The classic version, also oval, is also widely used. The French brand was already sold out on Thursday evening and expected a delivery in the night.

Devil / D.Racing users include CRG Racing Team, Praga Kart Racing DR, Energy Corse.

Elto remained more traditional, but equally effective with the new oval muffler.

TM is faithful to its Elto model and round section, but has developed a large diameter bend upstream.

Vortex has worked on a silencer that abandons the original cylindrical shape. It has a noise level around 104 db and leading performance.

At the French tuner Liegois, a second muffler was grafted, which limits the noise, but increases the weight of the machine.

Tec-Sav is preparing its own silencer, quite revolutionary, but they are using safer and proven equipment at Sarno. In any case, the new regulations allowed the technicians to engage in all-out search by showing a lot of imagination. It should be analyzed carefully to judge the performance and the price of silence at the end of the competition.
