No aftermarket exhaust is legal, be it for a car or a bike. Every time you buy one there is a note on it that says "for off road and race use only" So no... but you won't get pulled over. And as long as your shop isn't anal, you shouldn't have a problem with inspections. I had no front signals, a crash cage, a 12 bar and the bike was beat to hell. But it still passed inspection.
yeah i think he meant for bikes....obviously there are legal aftermarket exhaust for cars.
you wont get a ticket. roadstain, what do u mean by shop? inspections are done by the cops...in which case its funny but they dont care about aftermarket exhausts. my rr passed with a two bros c/f exhaust that said right on it "for off road use only" and it passed salvage rebuilt inspection with flying colors.
so to answer the original question...if i can pass police inspection with a loud as shit (it seriously was really freakin loud) illegal exhaust, im pretty sure you wont get a ticket, let alone pulled over for your exhaust.
