using titanium for the exhaust down pipe (k1 model link pipe is black, k2 model link pipe is polished titanium) and the inside of the silencer, enabled the 1000s exhaust system to become lighter than that of the 750. titanium was also used in the front fork (titanium-nitride) to coat the stanchions. an exhaust tuning valve had been mounted inside the exhaust pipe. using a servo the system dynamically adjusted the exhaust back pressure, according to engine speed, throttle position, and gear selection for increased torque, lower emissions, and decreased noise—the (stock) exhaust noise of the gsx-r1000 is notably lower than that of the gsx-r600.
