Spark Yamaha MT-09 "Grid-O Double" Full Exhaust System (Euro5) (2021+)

Spark Exhaust Technology Yamaha MT-09 "Grid-O Double" full exhaust system. Constructed with two (2) titanium racing style silencers (exiting from the lower left and right sides), special racing 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 and then combining with a high-performance racing catalyst 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 dark and enveloping sound as well as a unique design. Handcrafted in Italy. Ultra lightweight approximately 5.6kg (20% 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. *Does not include removable DB Killer.
