STI exhaust crackling/cracking

So after messing with my intake my exhaust was making some crackling which I assumed was me running rich and after-firing. However today I took the car out for a run WOT and couldn't here any after-fires in between shifts or upon deceleration.

When I got home and was letting the car cool down, I could again here what sounded like crackling. Upon further examination it doesn't seem to be after-fires but something in or on the exhaust crackling/cracking, it kind of sounds like metal cooling down and contracting, but it happens at all times, not just cool down, so it couldn't be that.

Any suggestions or am I just being paranoid?

could be two things. your heat shield on your uppipe is cracked. Mine was when I replaced it with the maddad uppipe. I know the noise you are talking about. I guess is is common on the sti for our years.

Or you are paranoid and it is normal.

Does it make the noise when it is idle? If so I would say its the heat shield. Which is a pain in the arse to get to.

 
Yeah it makes it when it idles, or if I rev when it comes down to about 1000 it gets a little louder. I guess next nice day we have I will toss it on some stands and see what in the hell is going on.

Yea, use something to tap it with and see if the noise is there. I barly noticed mine was cracked till I started taking pics of the uppipe to put up for sale. Then I realized the noise I was hearing sometimes, must have been coming from there.
