Question Exhaust Noise! Hmmmm

I'm getting an exhaust noise from the headers (I think) Is this a common problem, and if so is it a gasket, or are the headers prone to cracking. I'm talking 88000 miles here! If it is the header, what kind of a job is it to change?

The later model steel tubing headers crack in the crux of the Y on the 1-4 cylinder segment because the engine mounts collapse and this lets the exhaust pipe to the CAT twist it. The 2-3 segment doesn't have the large angle that the other has so you don't see it crack. This problem was "fixed" by putting a bellows segment in the 1 cylinder down tube.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?
