Broken tii manifold replacement

I’ve searched for a bit but most the threads I’ve found were older and usually about putting a tii manifold onto a non tii. 

 

I have a tii engine/manifold but the manifold has broken at one of the bolts to the collector. It doesn’t seem to be causing problems now but I imagine I can’t ignore it forever. Repairing it seems like a long shot so I’d rather replace. Should I buy the next used tii manifold that pops up here or try the IE stage 2 headers/full exhaust? The IE set up claims a small performance bump and some extra noise, neither of which I would mind. The car is only street driven, no emissions testing. 

 

Any insight or personal experience would be appreciated.

First, I'd say, don't mess with it until you have to!

 

Then- this could be welded up, redrilled, tapped, faced and it'd be good

as new.  

 

But if an inexpensive manifold shows up, that's going to be cheaper.

 

Not a huge header fan,

+1  The missing piece where it is won't cause leak.  (Save you some weight too :D)

Wrong stud bolt will cause that. Make sure to use 07119909117 stud bolts if decided to repair or replace at some point time.

So, let's assume tii and non-tii exhaust manifolds function in a similar manner and perform about the same. 

Are they interchangable - size, fitment, stud holes, etc.?

Thanks.

...except a MASSIVE loss of power at.... errr... probably about nowhere.  

I wonder if the different manifold dimensions were for tuning to the tii intake

and compression ratio, rather than overall flow.

Given the numbers Pat got some years back...
