The go to for increased performance over the Biturbo, but all around quiet exhaust to keep the neighbors and police off your back. Retains low end, but midrange and top end are increased much more than the Biturbo. Well designed exhaust.
Fits all A3 and A35 based Tomos mopeds besides the Revival. Mounts up easy to most. May need to drill another hole on the rear bracket to line up on some. Others needs the mounting bracket bent a little for pedal clearance. It is worth the extra little work for the power increase.
*This is Version 1 bracket. Different but still for A3/A35.
