I don´t care for the dual exhaust. Yosh/Suzuki AMA superbikes don´t use them. Suzuki had to use them because of new emissionxs standards to produce more air flow to get the power. I removed them and put on the Two Brothers V.A.L.E. system, which removed 20-25 pounds and sound excellent. Best system for the money. If you´d like a photo email me at mnadzieja01@hotmail.com
