An Exhausting Problem

    I have a part time job delivering pizza at night.  It is a fun job, and a good way to earn a few extra bucks.  On Friday, June 1st I was out on a delivery.  I was headed to the North Highlands, making the turn from Rt. 301 East to Rt. 9. North.  As I finished the turn, and started pressing the gas to accelerate on Rt. 9, the car suddenly got very loud.  I let off the gas, and got back on it a couple of times before I convinced myself that the noise was indeed coming from my car.  When I got to the house I was delivering at, after dropping off the food, I took a quick look under the car.  Everything seemed to be in place, nothing was hanging down, so I went on my way.  It was pretty loud, and the car's power was down, especially at low RPM, but it was useable.  I finished the night's work, and drove the car home.
     The next morning, I had a more thorough look, and discovered that the "Y" pipe had broken completely off at teh flange where it attaches to the catalytic converter.  Since a good bit of the "Y" pipe had significant rust, I decided that a replacement would be in order.  Since Saturday was already booked pretty much solid for me, I went to the auto parts store Sunday, and picked up the new pipe.  Unfortunately, I forgot to buy the necessary gaskets.
     On Monday, the 4th of June, it rained pretty much all day, and I had a doctor's appointment that I had forgotten about, but Tuesday morning it was clear, and the parking lot was dry, so I got to work.  Basically, I needed to remove six bolts that attach the pipe to the manifolds, one bolt that clamps the pipe in place, and the O2 sensor.  I started with the manifold bolts figuring they would be the most difficult, and the clamp would hold the pipe in place while I removed them.  The first bolt on the front manifold came right out, and I figured I was in trouble then.  The second bolt turned about one full turn, then froze up tight.  I sprayed it down good with Liquid Wrench, but it wasn't moving.  After some searching, I couldn't find a long enough 1/2 inch drive extension to reach it, and the only 17mm 3/8 inch socket I had was 16 point, which I was afraid would round off the bolt, so I left that one alone.
