    Hello all,
    Aside from the catalytic converter,the blower, and the belt associated with it, is there other components to the emission system on the 308?
    Are FI and carborated different in the above equipment list?
    Are the components visible from the engine compartment?
    Thanks in advance for sharing your knowledge

    Or visible but the charcoal canister and EGR valve should be in good working condition.

    Are you planning to remove all the CAT related equipment? Im thinking about doing the same...depending on all the requirements and pros vs cons

    You can look at the Parts Diagrams for the various cars of interest and see the differences in the emission equipment.

    Don’t do it, man.
    Your resale value to several states will be shot. I’m trying to buy one that is intact for So Cal.
    If you do, keep everything and put back before any sale consideration.

    All I can say about this is: If you have never driven a 308 with ALL of the DOT garbage taken off, then you have not experienced the true performance of this model. The car was never designed with all that stuff in mind. Everything was added later because they had to not because they wanted to. Hell, the bumpers alone are close to two hundred pounds! Not to mention the constricted breathing on the carb cars.

    Well, where to start:

    The North American cars beginning in 1976/77 had R1/R2 points and a microswitch to control them.
    Air pumps are the most visible, but the charcoal canister and tubing is important (and not an engine power loss.

    For 1978 it got more involved, adding catalysts, and also there's a flap in the air box snout that solenoids closed.
    These cars were stinky in the garage.

    I can see losing the cam driven air injection, that always seemed to be risky. You could do the same with an electric pump.
    Some plug the nozzles, which can melt and bend in the head, and plug the openings.

    Altering the CATS is against the law and as some noted ANY removal does reflect on future markets for the car.
    Always, seeing where you are on the A/F and 4 gas analyzer tells you if it's better, or worse.

    NON CAT cars are valuable, for a reason!!!!
