I ment to put that exhaust thing. And why take the line off when you can just blow right into the muffler. Worked for me. Probably takes a little more huffing though. And once the car's been run the taste of the exhaust is not satisfying. And as popper said, "this stuff doesnt taste very good" is most definetly correct. Although somtimes it tasted like cotton candy with some added nitro ingredient in it.
