Special engraved Akrapovic verification code on the muffler inlet cap.

Akrapovic Racing and Evolution exhaust systems are the top of the line of the Akrapovic range, designed for riders who demand the most from their exhaust system in terms of both quality and performance. The Racing and Evolution versions for the Suzuki differ only in their materials. The header tubes for both systems (including the Evolution 2) partially formed using HYDROFORMING technology!

NOTE1: We have also developed an Akrapovic EVOLUTION 2 exhaust system for the Suzuki GSX-R 1000, which is intended only for races and championships which allow louder exhaust systems – 107 dB. The EVOLUTION 2 differs from the EVOLUTION 1 and RACING systems in the design of the muffler. The muffler is shorter and louder (103 dB) than the muffler for the EVOLUTION 1 and RACING systems. The Akrapovic carbon-fiber bracket is mandatory (instead of optional as for the RACING and EVOLUTION 1). The EVOLUTION 2 is only suitable for certain types of competition!

NOTE2: Racing, Evolution, and Evolution 2 systems with the HEXAGONAL muffler are also available for the 2005-2006 Suzuki GSX-R 1000. Performance is identical to the oval muffler.

Performance

Measurements of the Akrapovic EVOLUTION 1 system on the SUZUKI GSX-R 1000 (without noise damper):

Power: the purpose of the Akrapovic Evolution system can be seen from the power curve. The system provides a linear increase throughout almost the entire range, and the greatest increase is at the very top of the range. With the Evolution the rear wheel puts out a huge 170 HP at 12000 rpm. The max. increased power is a healthy 11.4 HP at 12250 rpm.
Torque: the torque curve also reflects the exhaust system upgrade. The engine is more responsive between 3000 and 4000 rpm, after which its torque response dips slightly below that of the stock system, but from 5600 rpm on the engine is again more lively. The increase extends into the overrev range.
