    Exhaust heat riser - is it open or closed?

    It goes in the counter weight slot first and the the wound return spring slides in the slot. Try to google the install directions for that rebuild kit.

    Exhaust heat riser - is it open or closed?

    I do not see the stop spring. You are right on which way it turns. We used to free a lot of them up. Mopar used to make a heat riser penetrant and lube. Lube and let sit. Tap on each end of the shaft along with trying to turn it by the weight. Keep doing that and it might free up.

    Exhaust heat riser - is it open or closed?

    The counter weight is machined for the stop spring . If the stop pin is still in the manifold you should be able to figure it out. Looking at google images might help. Or just drop the pipe and see where the flap is.

    Catalytic converts with sniper EFI? Due to health related problems

    Even with cats you will still get some until you fix why it is getting in the car. And if really think your car is the problem how about all the cars, trucks, and cycles that are sitting at the stop sign with you. You should be smelling them long before yours.

    Which exhaust tips for 3” exhaust?

    I use the band and position them correctly. They are not visible unless you are on your back. Clamps were used from the factory. Welding degrades the materials and is a sore spot for discoloration. Plus 3 inch fits very tight and once welded its pretty much permanent and you had better pray it...

    Which exhaust tips for 3” exhaust?

    I have the TTI 3 inch and they fit and look correct. I would not trust the others as most likely they are poor quality knock offs.

    CPPA and TTI same design headers?

    Just Google CPPA headers lots of different discussions.

    CPPA and TTI same design headers?

    Who knows. Just expect to have to make modifications. The kits they claim are bolt on do not always fit without some sort of modifications.
