135DD Megaphone Exhaust for Ducati 848/1098/1198 - Full System:
The next generation in Double Dog exhausts, developed for performance gain and weight reduction for serious track and race superbikes - the 135DD adds torque/horsepower from the mid range to top end, with huge gains over the stock system and significant gains over the Termi race system.
Weight reduction and mass shift:
The 135DD megaphone and full titanium system weighs 9lbs and the stock system is 22bs - that's 13lbs removed and most of this weight is in the stock mufflers which are high up under the seat - well away from the center of mass. Shedding that weight from under the seat is a big deal, and much more important than reducing the same weight closer to the center of mass. You will feel the difference immediately, with a very different 'flickable' chassis balance - changing direction more like a light 600.
Power gain:
In an otherwise stock 1198, the 135DD adds over 10bhp at 6,000rpm compared to the Termi race system (which is likewise stronger than the stock exhaust system). See the dyno charts for the strong torque and horsepower gains through the midrange, converging with the Termi horsepower at peak.You will feel that kind of power/torque gain on the 'butt dyno' immediately....
Performance gain:
It's not all about horsepower. Combining the 135DD power gain with weight loss from high up away from the center of mass is a performance transformation. The peak torque/weight ratio jumps from 0.200 (ft/lb/lb) to 0.218 - an increase of 9%. You will feel that jump...
135DD notes:
- The 135DD can be used with either stock or Termi ECUs, however Double Dog Moto has developed a specific engine map for the Nemesis ECU to fully tap the power gain available from the extra breathing the megaphone provides. This map is available via email for anyone with the Nemesis ECU, and would only need dyno modification for those in high altitudes or with significant engine modifications.
- Removable db restrictor cap for tracks with more stringent sound restrictions.
- Megaphone is TIG welded from thin wall stainless steel. The 2 into 1 junction and headers are made from titanium and they come with all stainless steel mounting hardware and instructions for installation. 135DD muffler comes in polished stainless only.
- Recommended for race or track use. Like all race exhaust systems, the 135DD does not comply with emissions and sound laws in some States. As a guide to the sound level, the 135DD without the restrictor was developed to be just within the 103dB limit at Infineon Raceway in CA (measured a long way from the bike) - i.e. loud!
- Hear and see clips of the 135DD in action on various Ducatis in the movie section.
