QD - Panigale Streetfighter V4 slip-on
Italian exhaust manufacturer QD ( Milan ) has introduced a new system for the Ducati Panigale Streetfighter V4 - using the stock manifolds and double 52 mm diameter connection pipes where the two catalytic converters are used . A 2-in-1 connection pipe merges the flows into a common 60 mm diameter pipe where a valve , controlled by the stock servomotor , lowers the noise level to meet the homologation limits .
Italian specialist Polini Motori has added to its range of upgrade , service and repair products for Yamaha scooters equipped with Minarelli engines ( CY , MY , CW models ) with this new ' Polini For Race ' 12 mm crankshaft . Designed , engineered and tested to improve and increase performance and durability , the billet aluminium , precision CNC-machined connecting rod
The system ends with a double link pipe and two titanium silencers from QD ' s ' Gunshot Dark Matter ' series , in matt black ceramic coated finish , with GP style mesh grids in the carbon fibre end caps hiding the 2 dB killers . All the pipework is in TIG welded stainless steel with gas injection " to obtain a perfect inner surface , void
can be used with 12 mm special pistons as an alternative to the original 10 mm piston pin . They are equipped with the connecting rod to be installed with the new improved piston pins . " Perfectly balanced to reduce vibrations and power loss , they are thermically treated to increase their resistance . These ' Polini For Race ' 12 mm crankshafts are designed for use with the cast iron 40 cc / 70 cc cylinder kits in up to 14 hp applications . Available for horizontal and vertical applications ". Polini Motori is also announcing a new range of street and racing cylinder kits for the 12 mm CY , MY , and CW Minarelli engines that include a precisionmachined cast iron cylinder with improved , reduced friction cylinder-piston sliding . The exhaust ports have been designed to work in line both with the Polini original and Scooter Team mufflers . The racing version has been designed to achieve racing performance and to work in line both with the Polini original and all the gas turbulence and maximise the flow . " The system fits perfectly with the passenger footrests thanks to two small additional brackets supplied in the package that allow their relocation in a wider position ". A carbon fibre heatshield is in development and will be released soon . " The power achieved with this system is impressive , + 12 hp at the rear wheel in racing configuration with the race map - the tool to reflash the stock ECU is sold separately as an option ". As with all QD Exhaust products , this system is sold with a SERVICE CARD that allows the owner to extend to a 30-month warranty programme and to download the European certification .
