GOAL
The 2003 Suzuki GSX-R 1000 is a real attention-getter. Its character is obvious,and
with regard to our major involvement in the sport of motorcycle racing, the development
of an Akrapovic exhaust system for this model was a foregone conclusion.
It was developed based on 2002 model, with a number of modifications and improvements.
The Akrapovic RACING and EVOLUTION exhaust system for the 2003 Suzuki GSX-R 1000
will deliver results in a big way.
The RACING &EVOLUTION lines guarantee extreme performance. Increased power
at the top of the rpm range gives the rider what he wants: fast, high-energy riding
near the physical limit. The benefits you will gain from these systems will astound
you. The development of these systems was orientated towards this goal. In order
to ensure a better match with the new Suzuki,a great deal of attention was paid
to improving performance in the high end of the rpm range.
When you purchase a RACING or EVOLUTION exhaust system,you receive the same attention
given to riders on the world racing scene, since these lines are developed by
the same team of professionals using the same development criteria and potentials.
Both systems were developed on stock set-up bikes (frame and engine) and do not
require any additional modification.
Occasionally,our testing indicates that it is necessary to install interference
crossover tubes between the header tubes in order to obtain maximum performance.
This was the case for the exhaust systems in question.
Both the RACING and EVOLUTION systems also come equipped with a fitting for installing
a lambda sensor.
The two systems differ only in their materials.The RACING system is made of high-quality
stainless steel, while the EVOLUTION system uses titanium. In both systems, the
tubes are made of welded conical elements; the welds alone are a pleasure to look
at. Unfortunately they will be visible only during the installation of the exhaust
system, since the cowling of the Suzuki will cover the tubes when it is reinstalled.
The system ’s 4-2-1 configuration is fixed with free-floating connections which
are held together with high-quality silicon-shielded tensioning springs.
The muffler for both systems is the familiar Akrapovic oval. The outer sleeve
of the muffler can be ordered in either race-ready carbon-fiber or the elegant
satin sheen of titanium. The difference is only in the material; all other characteristics
(sound and performance) are identical. The interior metal parts of the muffler
are made exclusively of titanium in order to guarantee minimum weight. The muffler
is attached to the stock chassis hanging bracket using the renowned Akrapovic
carbon-fiber clamp.
NOTE:
A carbon-fiber chassis hanging bracket is also available. When installed,the muffler
is hung in a slightly higher position using the same link pipe.
Measurements of the EVOLUTION system for the Suzuki GSX-R 1000:
POWER:
Since this motorcycle was designed especially for racing, we were prepared to
sacrifice some performance in the lower rpm range. The EVOLUTION system starts
to show its cards from 5400 rpm on. The improvement over the stock power curve
is clear and steady all the way to the top of the rpm range. At 11500 rpm, the
rear wheel receives 158.8 HP. With this kind of brute force, you’ll need all your
skill in order to keep the bike from getting away from you. The max.increased
power is a full 12.6 HP at 12000 rpm.
TORQUE:
The drop-out in the stock torque curve between 2800 and 3800 rpm is filled, otherwise
the torque curve is similar to the power curve: in comparison to the stock figures
somewhat lower performance at the lower end of the range, and from 5400 rpm on
increased toque and a wider torque band.
As the graphs show, the purpose of the Akrapovic RACING and EVOLUTION systems
is primarily to improve performance. But of course the aesthetic element has not
been forgotten. Both the RACING and EVOLUTION systems complement the superb lines
of the GSX-R exceptionally well. The augmentation of the sound is yet another
positive factor. The sound of the engine at higher revs will be clearly recognizable
even before the bike comes into view.
NOTE:
Due to the complicated process for removal of the stock exhaust (exhaust gas valve),
we recommend that the Akrapovic RACING or EVOLUTION systems for the Suzuki GSX-R
1000 be professionally installed. See instructions!
