Injectors or exhaust leak?

I searched on the topic but didn't find an answer so I'm cautiously asking - I have an '83 280ZX with an L28E. Apparently the injectors were replaced "recently" but there is a fairly loud ticking sound coming from the engine bay. It goes away after the engine has warmed up which makes me think its the exhaust gasket (there is also a broken exhaust stud closest to the firewall). I've been told that is probably the injectors but it seemed odd to me that it would go away once the car had warmed up. Is it normal for stock injectors to be noticeably louder when cold?

+1 to both posts above, ticking injectors don't go quiet after the engine is warm.

As well as a broken exhaust stud is a clear sign of where an exhaust leak is occuring or will occur soon, as there's nothing clamping that part of the exhaust gasket down to keep it from blowing out and causing a leak.
