I have an exhaust leak at the passanger side header near the fire wall. The car is an 86' GT and the headers are BBK ( the cheep shortys ). The shop that found the leak told me the header might be cracked or just the gasket is shot. Do these headers crack often ? I think they're about 5 yrs old.

Thanks for your help.

Ive seen it happen, and had it happen to my original mac headers, what's worse is they cracked in the center of where all the tubes meet, which is damn near impossible to diagnose with them on the car, always sounds like a flange leak.

I'b be sure first they aren't leaking at the gasket or where header meets the h pipe.

Believe it or not, header gaskets are easy to change.
