some of you may have been following my td04 build.. and know that i got a toyosports ss exhaust header. i've heard of and read several posts of users complaining that they crack a lot. my question is, why do they crack..? what is the real reason..?
a) is it that the tubing expands/contracts faster than the flange during normal use so the difference in rate causes the cracks..? would heat-wrapping the headers then prevent this..?
or
b) is it that the weight of the turbo and mani weighs down on the flange (if not braced) and the engine wiggling about during routine use causes the cracks..? would bracing them then prevent this..?
can someone clarify and give convincing reasons to the same..?
