Re: cast manifolds
a quality built stainless tubular shouldn't crack. if it does, it must either:
(a). be constructed out of a poor quality steel.
(b.) the quality of the welds are poor.
(c.) poor design, insufficient material thickness in essential locations like wastegate flanges.
(d) the manifold suffered some physical trauma i.e. crash or extreme heat.
(e.) its from ebay
what im getting at is dont brand all tubular manifolds as weak and prone to cracking, try a higher end tubular manifold, a lot more expensive, but with much better design and construction materials. or you could go cast. cast manifolds are capable of pushing plenty of power (whats your power/performance goals?) but the casting process is a lil more limited as far as design goes. look around and do some research on what you want from your next manifold, and take into consideration durability as a selling point.

Re: cast manifolds
Inlinepro all the way for a cast manifold! And through my experience with tubular manifolds
they all will crack. It just may take many, many years but it will one day especially if you
daily drive your car. Maybe with the materials available more recently they will be more
reliable and last much longer. It has been awhile since I have researched material for
manifolds so I can't say much.
