We removed the cat delete/ mid link and servo, to reduce weight and to add more performance to the Gsxr 600 with the black widow full race exhaust. This exhaust will work from 2011 to 2022 Gsxr 600 and 750. Total weight reduction is 3.5 lbs. You will notice the difference in acceleration and power gains.
