I have an 09 wr450f and I've heard that you either change the exhaust or modify the current one. Can someone give me an overview on what exhaust system to get or how to modify the one I have(stock). Also how much can headers make a difference.

Thanks that did help a lot but I thought certain mufflers and/or headers would give you more torque and/or hp.
