Does anyone have or know of a link detailing the laws regarding emissions for older cars? (1969).Couldn't find much on the HTA'a website. I keep getting tickets by the same guy for excessive noise, improper exhaust etc etc.
Plz and thanks.
Emissions vary vehicle by vehicle, and most police don't know what is legal. If an engine modification is done to a vehicle, the higher not lowest emission standard must be met based on the year of modified part. EG. EFI motor in non EFI car, means cats, O2 sensors etc must be installed because they were part of the emissions of that year of motor, even if it's in a classic car. That said, there are no emission laws for '69 cars or trucks, but they can make you upgrade if you have an EFI motor. But if you put a throttlebody injection system on in place of the carb, I don't think they can do anything.
Emission standards were applied when unleaded gas was introduced as the fuel for that year and engine size, as well as GVW for trucks. Pick '76 for example. 4 cylinders, were running on unleaded gas, and came with catalytic converters, where most V8s didn't. '77 had a larger number of vehicles running on unleaded, and '78 even more. Not sure what year, but light duty trucks had emissions standards applied before heavier trucks. If you can remember, at the gas stations, leaded gas nozzles where bigger than unleaded, and the throat on filler necks wouldn't allow leaded gas nozzle to enter an unleaded car.
Exhaust systems must be hole free(leak proof), and clear (side or rear dump) the passenger compartment including trunk area in cars, and cargo space in SUVs, and just past cab in trucks. For classic cars, this means you can't legally have your exhaust system stop under the car, but have pipe continue to rear or side, preferably after the rear tires, to vent exhaust away from windows. As far as what type of muffler is legal based on noise levels, some CherryBombs aren't even though Canadian Tire sells them.
BTW, welcome to the club. I've been hassled for years, for modifications I've done.
