Spark Exhaust Technology Ducati Monster 937 Exhaust. The new design combines the timeless and essential round shape of the round titanium case with the latest generation technology of 5-Axis CNC machining. The standard side mounted dual titanium slip-ons (SP-GDU0839TOM N-R-C) come with an AISI-304 stainless steel 1-into-2 link pipe. The silencer end cap is the element that enriches the titanium silencer and customizes the bike with a unique touch thanks to the different colors finished in Red (SP-GDU0839TOMR), Black (SP-GDU0839TOMN) or Carbon (SP-GDU0839TOMC). The precision milled endcap is a technical and aesthetic element with perforation that allows it to be lighter. This very light slip-on, with silencers made entirely of titanium, reduces the weight by 1kg compared to the original. Moreover, thanks to the inner diameters and outlet sizing, the slip-on allows a increase of 2hp with the Euro5 approved version, without any other modification to the motorbike. Dyno Tested for maximum horsepower increase over stock. Re-use OEM heat shield. Handcrafted in Italy.
