OK so I know the motor is the same for the 570, does that mean the exhaust is the same too? I am looking at doing the ECM upgrade at some point but for now I want new exhaust and need it coated. Who makes one for this bike? I see stuff out there for the 570 but not the 450? I’m wondering if diameter of tube is the same as is bolt mounting surface. Why an I finding so little aftermarket support for the 450?
