Hey guys im a newbie when it comes to knowing the guts of a motorbike but I know how to ride one well enough. Anyway straight to the point, on a 2015 ER-6n, is the catalytic converter that big chunky metal piece just behind the exhaust tip? If i want to upgrade the exhaust does that mean I have to remove the cat conv.? I dont want to increase pollution but I want my bike to be louder so that every car knows where i am all the time. Thanks!
