    remove your emissions equipment;

    Cap off / unplug the EGR, Remove the Cat Convertor, Unplug the Charcoal Canister, ect. Then unplug all the other vacuum hoses to the carb keeping the vacuum advance, brake booster, and PCV hooked up. Wire open the heat riser valve ( if you still have one on the PS exhaust manifold )

    But I have to ask why ?? Really no great power to be found with an emissions delete. I actually am looking at replacing my hollowed out cat-convertor ( car stinks in a drive thru or in heavy traffic without it ), EGR, and Charcoal Canister. I want to at least pass a basic visual inspection if MTO yanks me over.

    Oh ok I thought that the emissions crap would hurt the performance of the car. My car already doesn't have a cat and I can't tell when it smells a bit. So if I remove the charcoal canister would that hurt the engine at all?

    I suggest you leave the EGR in place, although it recirculates burnt fuel it lowers the combustion chamber temps which allow you to run your timing with more advance..for cats they have spun cats that were designed for race cars which have virtually no resistance...get caught without either they can tow and impound your car and you get a $385.00 ticket

    For Canada, if a car is older than 1987 (mines 86) Ido not require cats because my car doesn't need emissions

    Oh? I was told that before by one of my friends . I've seen lots of cars older than mines with no sort of fake cat on and they seemed fine. My car has passed safety and cert with the exhaust like that

    Well no cop has even told me yet that my exhaust is illegal, even when they pulled me over for thinking i didnt have my seatbelt on... And the reason i want to rid of the emissions crap is because it clutter up the engine bay. And since i dont need emissions anymore, why bother having it...
