Elto Racing's TD/3 INOX 39/EX-SI/24 silent exhaust is specially designed for KZ and KZ2 karts. This model is round and has been developed to reduce the maximum speed of the engine, thus providing optimal performance. Made of stainless steel, this exhaust is lighter than the old TD models, making it an ideal choice for karting drivers looking to improve the performance and durability of their engine. This new steel model is approved for national and international categories by CIK-FIA under approval number 039-SE-24.
