Compatible with original silencer. Optional db killer for further dB level reduction: G9976 (104dB)
Performance: Considerable weight saving and elimination of the heat caused by the original catalyst. The great attention Spark R&D paid to the development and sizing of the collector allows to eliminate the annoying torque holes around 3000 - 5000 rpm and noticeably improve acceleration. More torque and power at low and medium rpm (+ 3 hp at 5000 RPM) for better use on the road.
The collector is provided with a valve simulator allowing the connection of the original valve cables. As a result, the malfunction indicator does not switch on even if the valve is removed for race use.
