Diffrence between sandard pipes and vance and hines in power

SOURCE: Question about Vance and Hines quiet baffles

about 3-5db but you must remember db is not a linear scale but logirythmic. basicallyy the baffles will remove the harsh rasp off the pipe and make them deep in sound, when cold they will be as loud as normal but once they have some heat in them they quieten down

Whenever I have a question about an aftermarket part - I contact the manufacturer, they are very helpful, but to answer your question, In general, if u get the correct part for your model bike, it should mount the same as the OEM part you;re replacing

Depending on the pipes you purchased, they will be stamped as to whether or not they meet noise requirements. Many if not most aftermarket pipes do not. Sorry.
