heres what i did with my exhaust ticket... took my 50-state legal papers that came with it to court, judge said that doesn't matter anything that isn't a factory replacement is illegal, i played dumb and acted equally angered at the exhaust manufactorer and said shit if i had known that i wouldn't have even bought it damn they ripped me off of 500$ because they told me it was legal... and then the judge smiled and told me how in life you'll find what people tell you and what is really true is often different, i said yea it was a expensive lesson and told him if he gave me a few weeks i would find a stock replacement and return, he said just bring me pictures and a receipt... brought him a copy of my ebay invoice for a stock exhaust and a polaroid of it on my car and he dismissed it... if you dont mind going back to stock, atleast long enough to take a picture, then i'd try this... if you want to keep it on the car then your screwed, if you try and argue how its quiet and 50 state legal and stuff you will only further anger the judge... if your morals dont bother you just find a same color car with a stock exhaust and take a picture of it and say its yours, and drive someone else's car to court so the cop that pulled you doesn't see it
