Born to improve performance on 2 strokes street bikes, Street 2T ("2T" means 2 strokes) exhausts are made with a muffler and a silencer. Muffler is made with several sections, manually coupled, welded and checked to ensure a good torque increase from lower rpm. Muffler is treated with transparent paint, to protect and enlight these features. Depending on model, silencer is available in kevlar, carbon fibre or aluminium. Street 2T systems are available in racing and street legal version, depending on exhaust.
