Exhaust pipe Yamaha MT-10 -'21 decatalyst stainless Mass

Mass exhaust manifold made of AISI 304 stainless steel with TIG welding. The Mass decatalyst is complete with pre-silencer to lower phonometric emissions. Available in a racing version without catalytic converter or with a sports catalytic converter: this allows the heavy and bulky original ceramic catalytic converter to be eliminated and replaced with a lightweight high-performance metal catalytic converter that does not throttle the engine, allowing it to express its full potential while remaining within the limits of polluting emissions. Compatible with both the stock exhaust and any Mass exhaust terminal.
