SUPERTRAPP 2 IN 1 COMPLETE MOTORCYCLE EXHAUST FOR HARLEY DAVIDSON SPORTSTER 86-03

The SuperTrapp discharge gives more power and less weight and provides the possibility to adjust the return pressure of the exhaust gases thus increasing the power curve throughout the arc of the revs. The SuperTrapp exhaust is equipped with a patented system of 4" disks at the exit. Adding disks increases the size of the exhaust opening by reducing the gas return pressure. The possibility to add or remove discs in a very simple way makes it possible to adjust the system to have maximum power with standard of legal noise or with a rhombus from Drag Racing. Stainless steel is available satin-finished for a racing or polished look and fit into the original attacks. SuperTrapp declares that, adapting the jets of the carburetor, you can get an increase of 10 HP compared to the original system. SuperTrapp discharges are recommended by almost all trainers and are mounted by the Harley-Davidson racing team. Available in complete sets or only collectors.

For Sportster 883-1100-1200 from 1986 to 2003, except models with advanced SATINATO series controls
