Program
We have prepared Akrapovic EVOLUTION STREET LEGAL and EVOLUTION (open) systems for the S version of the mighty Italian rocket, which have a major effect on the performance of the twin. In addition to the performance, the systems are also visually appealing, and noticeably different from our Evolution system for the 999 Biposto. In addition to the EVOLUTION STREET LEGAL version for the 999 S (muffler length 350 mm) in-tended for everyday riders, we have also developed an EVOLUTION (open) version with a shorter, 300 mm canister, which fits well with the single-seater “monoposto” cowling and does not allow the rear light bracket and license-plate holder to be mounted. This version is louder than the EVOLUTION STREET LEGAL. We have also developed optional titanium header tubes for both versions.
PERFORMANCE
Measurements of the Akrapovic EVOLUTION STREET LEGAL system (muffler: 350 mm) on the DUCATI 999 S (without noise damper):
Power: the Italian twin gets the strongest effect from the Akrapovic EVOLUTION STREET LEGAL exhaust system in the range from 3000 rpm to 6000 rpm and above 8000 rpm. The already high-performance engine receives new air passages, which really open up the performance potential which can be seen on the graph of the power curve. The max. increased power is 9 HP at 4800 rpm, with max. power of 129.8 HP at 10250 rpm.Torque: the torque results are even better. Between 3000 and 6000 rpm the torque delivery is exceptional; there will be no need to worry about a lack of grunt at low revs. This also guarantees smooth riding in high gears at low revs. And of course, in keeping with the character of the EVOLUTION exhaust system, there is no lack of torque at high revs, either.
CONFIGURATION
The EVOLUTION STREET LEGAL system (350 mm version) is designed in a 2-1-2 configuration and is based on the previously developed Evolution system, so there are certain similarities. The conical header tubes are made of high-quality stainless steel, while the Y conical link pipe is made of titanium. The header assembly is composed of three parts: a front header tube and a rear header tube, which are both attached to the header tube connector (a combination of a collector and extensions of the front and rear header tubes) with free-floating joints held together using high-quality silicon-shielded tensioning springs. In order to maximize performance, all versions of the Akrapovic EVOLUTION systems for the 999S have interference crossover tubes installed between the header tubes. Each system also includes two fittings for installing lambda sensors.
The link pipe is a special Y shape and is attached to the header assembly using a free-floating joint, while it is welded to the muffler. The double inlet into the muffler is continued with dual outlet tubes at the back of the muffler. The muffler is very distinctive, with a quite different outlet cap from the Evolution system for the 999 Biposto. The dual outlet tubes give it a real “racing” look. The muffler is attached to the frame using a metal clamp. The outer sleeve is available only in titanium, which goes extremely well with the refined lines of the Ducati. The metal parts in the interior of the muffler are also made entirely of titanium.
All Akrapovic EVOLUTION exhaust systems for the Ducati 999S are also available with an optional car-bon-fiber heat shield which is mounted onto the link pipe. Due to the stock design of the motorcycle, the carbon-fiber bracket on the underside of the muffler carries the rear lights and the license-plate holder. As mentioned, the EVOLUTION (open) system with the 300 mm muffler does not allow the rear light bracket and license-plate holder to be mounted. The muffler includes special performance inserts mounted in both outlet tubes. These inserts are not intended to control the noise output of the system, and therefore the system is not intended for street use.
OPTIONS
An Akrapovic carbon-fiber heat shield is also available as an option. Titanium header tubes are also avail-able for both the EVOLUTION (open) and EVOLUTION STREET LEGAL versions.
