I bought a 2003 r1 on which the previous owner installed a stainless steel yoshimura rs-3 slip on. Some cop renowned for busting sportbikes for no reason gave me a 156$ ticket because my exhaust system is not legal, supposedly. the pipe wasnt modified and isnt noisier than the yamaha pipe (at idle at least) but im scared, i keep seeing on the website, not intended for street use and all, which is very bad. the previous owner told me he won in court with the same exhaust pipe, he had some kind of spec sheet that said the exhaust pipe is legal and sold in canada. so, where do i find that?
Laws on excess noise are very subjective, based on what the officer considers too loud You don't say where you live, so defining whether that specific setup is illegal is impossible, Legally, NO after market exhaust is automatically legal, you must use the exhaust provided by the manufacturer or risk a ticket. Certainly, legality in another jurisdiction is meaningless. On the other hand, if you ride you bike in a courteous manner, NOT intentionally revving the engine, you'll find few complaints. If you drive the opposite way, expect a lot of hassles.
