Sound is aggressive but not extreme so that it is perfect both for race track and road. 

A valve simulator is included in the box to simulate the presence of the original valve which is eliminated. Spark valve simulator prevents the error light from switching on. 

Specific diameters and tapers allow to highly improve performance without modifying map or original ECU. Incredible weight saving (-3,7 kg compared to the original).

Spark offers 2 different slip-ons:

- Konix Evo (109 db 5500rpm without DbKiller and 104 dB 5500rpm with optional dB killer) - GAP0402

For a complete full titanium system, it is possible to install Spark full titanium headers which are the result of Spark research and development carried out together with NUOVA M2 Racing Team during 2019 season. Such great work led to the victory of the National Trophy 1000 Championship with Eddi La Marra and the second place overall by Lorenzo Savadori in CIV Superbike Championship.
