[bgTercel]

Of late I've been having problems w/ my 94 tercel. My exhaust became progressively louder. The person that repaired it said they replaced the flexi-pipe. A few weeks later it became louder again. While replacing the spark plugs the other night, I noticed that the exhaust pipe had fallen from the exhaust manifold. I am guessing that the exhaust pipe was bolted to the manifold? I'm also guessing that the nuts have surreptitiously fallen off. Does anyone know what size I should look for at the hardware store? Any suggestions on the best way to repair this problem?

thx
