Stock h-pipe question

weld it back up i guess, just dump tha stock pipe and put on an aftermarket catted or uncatted h-pipe and delete tha whole air pump... grab a new serpentine at napa and you're good to go

Find out where it's disconnected and put a piece of heater hose bwteen the two ends -- or just reattach if it pulled off at a joint. It will connect up with some hoses that go to the air pump system on the engine.

The same thing happened on my convertible. I noticed the exhaust making the sound you are talking about. I looked under the car and saw that pipe broke. All you need to do is get some heater hose like 89MustangGX says and adapt it to the part that is broke.

When you pulled the pipe off, did you do it from under the car by pulling on it? Maybe you pulled it out of the pipe that it connects to by the header? Check the passenger side by following the pipe going from the air pump to where it splits and one goes to the head and one to the exhaust.
