    Not sure what this means as I'm not a mechanic but thought I would ask. I had my 300 out the other day. The car has duel exhaust all the way back. It was a little cold out so obviously I could see the exhaust smoke. But I was curious as to why smoke was shooting out one pipe and not the other. Only the driver side exhaust had clearly visible smoke while the passenger side had nothing. The car runs great, I haven't noticed any issues while running.

    Any help is appreciated, thanks.

    Maybe a cracked valve seal on the one bank

    Could it be that the exhaust crossover valve? on the passenger side manifold was closed? Once warmed up, it should be open.

    yep..Heat riser in the right exhaust manifold may be closed at idle to help warm up the engine.
    Not to worry.it is working normally.
    Goose the gas and you will see that both side expell exhaust.
    If not,check the heat riser to make sure it moves freely.

    I never thought of that, makes sense. When I noticed this I had just started the car after it had been sitting for almost a month. Next time I have it out when I come back home I'll see if I'm getting smoke out both pipes.

    Thanks everyone!
