Spark Yamaha MT-09 "Grid-O Double" Full Exhaust System (Race) (2021+)

Spark Exhaust Yamaha MT-09 "Grid-O Double" full exhaust system. Constructed with two (2) titanium silencers (exiting from the lower left and right sides), racing version without catalyst to the pre-silencer box, heat shield and stainless steel header. Spark R&D has been working extensively on the Japanese motorcycle from Yamaha enhancing the design, sound and performance of the 3-cylinder bike. Spark's long working experience on 3-cylinder engines, for example in Moto2 was an excellent starting point for sizing the manifold in the best possible way to improve the performance of the bike. The collectors derived from competition have a compensator and 3-in-1 pipe as the Moto2 systems. During the development great attention was paid to the sound, which is extremely dark at idle speed and maintains the spectacular 3-cylinder engine sound note. Spark full system improves performance and gives the motorcycle a unique look. Handcrafted in Italy. Ultra lightweight approximately 5.3kg (23% lighter than stock). Dyno Tested for maximum horsepower increase over stock. Racing Version for Maximum Performance. For perfect performance, throttle response and durability, ECU remapping is recommended.
