as for your leak, a mechanic once recommended cleaning up the leaky spot real good, and applying a gob of silicon to the outside of the pan if you can reach it. yeah, it's a hoopie way of doing things, but it can work really well

 

Sounds like a good idea. If i can isolate and reach the leak(s), i would most deffinately try it. On another note, if i was going to pipe it out which would be the best way to go? i was thinking single pipe with the new cat and muffler, but my friend suggested after the cat Y pipe it to duals. I personally think I would like the single pipe better, also i wouldn't have to pay for another muffler. Another question would be the size of pipe, currently i believe it's 2.25" in and out. A far as i know the exhaust is a lil rusty, but no where through except for right before the muffler. Other than that it looked fine.
