    nowI have a 72 Dart with a 318 headers and 2.250 duels that exit each side just in front of the tires. I had glass packs on it and they had too much of a crack to them so I went to Flomaster super 44s. now when I run it I get fluid spraying out of the exhaust. it don't smell like gas or feel like oil. could this be a condensate problem or is the timing just a coincidence and I need to look somewhere else?

    Thanks in advance

    For me step one would be determining what it is.

      Condensation in exhaust systems is common.

      Some factory systems even had drain holes.

        For every gallon of gas you burn a gallon of water is produced.
        It only does it during warm up i imagine,once exhaust heats up, the condensed water is cooked out of exhaust system.

          H2O is a byproduct of complete combustion. My 340 exhaust tips have drain holes. Gone soon as she warms up, all good! 65'

            Yes, theoretically a gas combustion engine should only produce carbon dioxide and water (IIRC).

            The more clean water you have dripping out of your exhaust, the cleaner and more efficient your engine is running.

            My 67 Coronet 318 dripped a significant amount of water, ran so smooth you could balance a pen on the air cleaner lid at 600 RPM and rev it, and got over 22 MPG highway.

              The glasspacks held the water in the packing, it was still there. Then it cooked out after the muffler warmed up.That's why cheap glasspacks usually rust out pdq.
              Your 44s IIRC are empty boxes, so there is nothing in them to prevent the incoming exhaust to blow across the water pooled inside them, and carry it the short distance to your dumps, as still a liquid.
              I drilled 1/8th" drain-holes at the lowest points of the mufflers, and also at the lowest points of my over-the-axle tailpipes, just for this reason. I'd rather have a bit of water on the floor, than blowing onto whatever is behind .
              My exhaust system is coming 19 years old and has no visible rust on it.Good thing! because that TTI stuff was not cheap; it's down to under $29 per year now.

                All good responces, I guess I have no problem. I was just kind of freaked at the situation I have never had this before, maybe I just pay closer attention to this car. Thanks

                yes if the water keeps flowing out after it's completely warmed up then you have problems! I was over at a friend's house and his kid was pouring water in his radiator and it was steadily coming out of his tail pipe! THAT'S A PROBLEM!

                Not necessarily.

                That Coronet dripped about 6-8 drops per minute after being warmed up.
                It did NOT drip until it got warm.
