First its a primary muffler delete as that is what the part being removed is called by BRP. The primary muffler. Replacing a muffler and other exhaust components on motorcycles is not illegal. Nor are they illegal to manufacture and sell. At least under current rules.
Second, there is no emissions inspection on motorcycles in ANY state. Not even California.
So it is not a Catalytic Converter?
