Akrapovic Street Legal Exhaust System BMW R1200GS / Adventure 2004-2009

Akrapovic has developed an easily recognizable Akrapovic 2-into-1 RACING system in order to satisfy riders who want to get the maximum power and torque out of their maxi-enduro machines. The GS1200 gets a major performance boost which will be very welcome for riders who like to ride in difficult terrain. In addition to the performance, the Akrapovic system is less than half the weight of the stock system. The new exhaust system will also be recognizable due to its sound, as the flat twin gets to breathe much more deeply. You will also save 4.77 kg compared to stock system.

• Racing System uses stainless steel header tubes and link pipe
• This system is a 2-into1 system

Power: Due to the enduro design of the motorcycle, the Racing System for the 1200 GS is designed to deliver a power increase throughout the rpm range. The fluctuations in the stock curve at around 4500 rpm are leveled, and max increased power of 8 HP is delivered at 4800 rpm. There is also a major increase around 6500 rpm. 

Torque: Torque delivery with the Akrapovic Racing System is improved, with the drop-outs in the stock curve filled. This system will supply more than enough power and torque for enduro and cross-country riding.

NOTE: Please check local laws before purchasing. Some modifications may be prohibited in some states.
